Book excerpt: Signal space diversity, which achieves reliable communication in fasting Rayleigh fading channel by creating redundancy in signal space, is a power- and bandwidth-efficient diversity technique. However, the complexity of the optimal receiver grows exponentially with the diversity order we designed to achieve. In this work, we concatenate the signal space diversity scheme with a outer convolutional code at the transmitter, at the receiver we use iterative demodulation and decoding. By utilizing the soft output from the outer soft-input soft-output (SISO) decoder, we can do soft interference cancellation. We proposed two kinds of Gaussian approximations to calculate the soft output of the demodulator, one is the vector Gaussian approximation, the other is the scalar Gaussian approximation. The complexity of the vector Gaussian approximation grows cubically with the designed diversity order, while the complexity of the scalar Gaussian approximation grows linear with the designed diversity order. Both of these two method can exploit the signal space diversity very well. We also applied the two Gaussian approximation methods to do iterative demodulation and decoding for the concatenation of convolutional code and lattice-based space-time block codes. Their performances are compared with the linear MMSE method. Also, we analyzed the behavior of the vector Gaussian approximation method by using EXIT chart analysis. When the convolutional code is concatenated with a modulator and a bit-interleaver is used in between, the mapping from bit sequences to the constellations affects the performance of the receiver very much. By a carefully designed mapping, we can achieve performance gain without adding additional complexity to the receiver or consuming any other resources. In our work, we considered the mapping from bit sequences to the space-time matrices. The mapping criterions are derived for the demodulator with perfect a priori and no a priori information. Optimized mappings are searched for some unitary space-time modulations schemes and non-coherent space-time modulation schemes. Spatial diversity is more and more widely used today. However, to have spatial diversity, multiple antennas should be equipped at the transmitter and/or the receiver. This would increase the cost and the size of the transceiver in the mobile station.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Space-time coding is an attractive technique to exploit the transmit diversity gain provided by a multiple-input multiple-output (MIMO) wireless system. Regarding a space-time code design, some important concerns are high rates, full diversity, large coding gain (diversity products) and low decoding complexity. However, a tradeoff exists among these goals and constructing a good code that optimizes some or all of these goals is a very practical and interesting problem that has attracted a lot of attention in the past 10 years. Furthermore, other design issues may also matter and should be taken into account when one considers certain special scenarios to which the space-time coding technique is applied. In this dissertation, we study both the code design at the transmitter side and the fast decoding algorithm at the receiver side for space-time coding. The first topic attempts to achieve both low decoding overhead and maximum (full) diversity for space-time block codes (STBC). By deploying a linear detector at the receiver, we can efficiently reduce the decoding complexity for an STBC and always obtain soft outputs that are desired when the STBC is concatenated with a channel code as in a real system. In this dissertation, we propose a design criterion for STBC to achieve full diversity with a zero-forcing (ZF) or minimum mean-square error (MMSE) receiver. Two families of STBC, orthogonal STBC (OSTBC) and Toeplitz codes, which are known to have full diversity with ZF or MMSE receiver, indeed meet this criterion, as one may expect. We also show that the symbol rates of STBC under this criterion are upper bounded by 1. Subsequently, we propose a novel family of STBC that satisfy the criterion and thus achieve full diversity with ZF or MMSE receiver. Our newly proposed STBC are constructed by overlapping the 2 x 2 Alamouti code and hence are named overlapped Alamouti codes. The new codes are close to orthogonal and have asymptotically optimal symbol rates. Simulation results show that overlapped Alamouti codes significantly outperform Toeplitz codes for any number of transmit antennas and also outperform OSTBC when the number of transmit antennas is above 4. The second topic concerns the design of space-time trellis codes (STTC) for their applications in cooperative communication systems, where transmission among different relay nodes that cooperate with each other is essentially asynchronous. A family of STTC that can achieve full cooperative diversity order regardless of the node transmission delays has been proposed and it was shown that the construction of this STTC family can be reduced to the design of binary matrices that can keep full row rank no matter how their rows are shifted. We call such matrices as shift-full-rank (SFR) matrices. We propose a systematic method to construct all the SFR matrices and, in particular, the shortest (square) SFR (SSFR) matrices that are attractive as the associated STTC require the fewest memories and hence the lowest decoding complexity. By relaxing the restriction imposed on SFR matrices, we also propose two matrix variations, q -SFR and LT-SFR matrices. In an extended cooperative system model with fractional symbol delays whose maximum value is specified, the STTC generated from q -SFR and LT-SFR matrices can still achieve asynchronous full diversity. As a result, more eligible generator matrices than SFR ones become available and some better STTC in terms of coding gain may be found. Finally, the third topic is to speed up the decoding algorithm for the vertical Bell Laboratories layered space-time (V-BLAST) scheme, a full rate STBC that however does not exploit any transmit diversity gain. A fast recursive algorithm for V-BLAST with the optimal ordered successive interference cancellation (SIC) detection has been proposed and two improved algorithms for it have also been independently introduced by different authors lately. We first incorporate the existing improvements into the original fast recursive algorithm to give an algorithm that is the fastest known one for the optimal SIC detection of V-BLAST. Then, we propose a further improvement from which two new algorithms result. Relative to the fastest known one from the existing improvements, one new algorithm has a speedup of 1:3 times in both the number of multiplications and the number of additions, and the other new algorithm requires less memory storage.

Available in PDF, EPUB and Kindle. Book excerpt: Space-time coding (STC) is a promising technique to achieve transmit diversity in Multiple-Input-Multiple-Output (MIMO) systems. Recently, space-time coding in a distributed fashion (DSTC) for cooperative relay networks attracts a lot of research interests. The design of space-time coding for cooperative relay networks has some new challenges which are different from the design of space-time coding for MIMO systems. The synchronization issue is one of the most important problems in the design of distributed space-time coding for cooperative communication systems since the cooperative systems are asynchronous in nature, e.g., there may exist timing errors and multiple frequency offsets in the cooperative systems. In this dissertation, we will discuss and study several designs of space-time coding for cooperative systems with different system models and in different asynchronous scenarios. In the first topic, we attempt to design very simple space-time coding schemes for cooperative systems with timing errors in Amplify-and-Forward (AF) mode. One of the major purposes is to make the relay nodes as simple as possible so that the relay nodes only need to implement very simple operations with a very low complexity. Another major purpose is to achieve full diversity and fast Maximum-Likelihood (ML) decoding at the receiver despite the existence of the timing errors. Except for the timing errors, the problem of multiple frequency offsets is another kind of asynchronous error which should be solved as well. In the second topic, we investigate the scenario that the timing errors and the multiple frequency offsets are existed simultaneously in the Decode-and-Forward (DF) cooperative systems. We adopt OFDM to combat the timing errors and propose an intercarrier interference (ICI) Self-Cancellation scheme to suppress the ICI caused by multiple frequency offsets. In the third topic, we consider the physical layer security issue in cooperative systems with timing errors. In order to avoid illegal interception of the eavesdropper in a cooperative system, we propose a distributed differential encoding/decoding scheme combined with deliberate signal randomization to achieve Low Probability of Interception (LPI) as well as to obtain full diversity regardless of the timing errors.

Available in PDF, EPUB and Kindle. Book excerpt: It is well understood that MIMO technology could enhance the reliability of wireless communication and increase the channel capacity. The design of space-time code to explore the benefit provided by the multi-antenna systems is of key importance. This dissertation addresses several issues concerning the design of space-time code. The following is a brief description of these issues and our contributions. Cyclic division algebra (CDA) has been introduced as a means to construct full-rate nonvanishing determinant STBC (space-time block code), which achieves the diversity-multiplexing trade-off and has a very good performance. There are two steps to construct CDA-based nonvanishing determinant STBC: construction of a cyclic extension over [Special characters omitted.] (i) and finding a non-norm element. For the first step we proposed a new up-to-down construction method. With this new method we find a broad range of cyclic extensions over [Special characters omitted.] (i), which encompasses all the previous constructions. For the second step, we give new criteria for the non-norm element. Non-norm elements found by these new criteria have smaller absolute values, hence the resulted STBC has a better coding gain. The well-known design criteria for space-time code is proposed by Guey-Fitz-Bell-Kuo in 1996 and Tarokh-Seshadri-Calderbank in 1998. The derivation of the design criteria is based on the assumption that the received signals are decoded with an ML receiver. One important issue seems to be long ignored: there is no design criterion for space-time code decoded with suboptimal receivers. Only until recently that Zhang-Liu-Wong and Shang-Xia studied the full diversity codes with linear receivers. We address the issue in a much broader sense. We proposed a more general receiver structure called PIC (partial interference cancellation) group decoding. A PIC group decoding can be viewed as an intermediate decoding algorithm between linear decoding and ML decoding. It encompasses both linear decoding and ML decoding as its two extremes. We also derived a design criterion for space-time codes with PIC receivers to achieve full diversity. The full diversity criteria for codes with ML receivers and linear receivers are special cases of our new design criterion. In many applications, wireless communication devices are limited by size or hardware complexity to one antenna. Cooperative communication was introduced for communication networks with single-antenna nodes to exploit the multi-path diversity. In cooperative communications, a few nodes positioned between the source node and destination node are served as the relay nodes. One important problem for cooperative communication networks is the time-asynchronism among the relay nodes. We propose a distributed space-time coding scheme called distributed linear convolutional space-time code (DLC-STC) to address this problem. We also give systematic construction methods of DLC-STC which achieves full diversity without time synchronization among the relay nodes. Furthermore, we show that our proposed DLC-STC achieves full diversity even with suboptimal receivers such as ZF/MMSE receiver and DFE receiver.

This book was released on 2011-05 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space- Time Block Coding (STBC) are used to improve the transmission reliably and spectral efficiency of MIMO systems. The cooperative communication techniques can avoid the difficulties of implementing actual antennas array by converting the single-input single-output (SISO) system into a virtual multiple-input multiple-output (MIMO) system. When STBC applied to cooperative diversity the system termed as Distributed Space Time Block Code (D-STBC). Most of the existing research assumes perfect synchronization among cooperative users in D-STBC. Unfortunately, perfect synchronization is almost impossible to be achieved. Therefore, most of the designed space-time codes are no longer valid. There are different research efforts to overcome this problem; most of which has high decoding complexity. In this research, two low decoding complexity schemes for imperfect synchronized D-STBC have been proposed. The first scheme is based on the principle of parallel interference cancellation (PIC), whereas the other is based on successive interference cancellation (SIC). These approaches have been proved to be a very effective in suppressing the impact of imperfect synchronization.

Available in PDF, EPUB and Kindle. Book excerpt: It is well understood that multiple antennas can be used to effectively combat the fading in wireless links and increase the channel capacity by exploiting the spatial diversity. This dissertation addresses two main techniques to approach the increased capacity: space-time coding/modulation and iterative decoding. For space-time coding we proposed a systematic and closed form construction of complex orthogonal space-time block codes of rates (k + 1)/(2 k) for 2 k or 2 k & minus; 1 transmit antennas, where k is any positive integer. The rates of our construction are the maximum rates for complex orthogonal designs without linear processing. Furthermore, another closed form construction is proposed when the number of transmit antennas is a multiple of 4, where the delay size is only half of the designs known previously. This dissertation also presented a new recursive space-time trellis codes design from differential encoding, which can be applied to serially concatenated system to achieve turbo gain through iterative decoding. We proposed a new design criterion to obtain the recursive trellis with larger error event length, which makes it possible to increase the performance by careful design of the STBC mapped to the states. By using the new criterion we developed a class of recursive space-time trellis with number of states M 2 for any size of constellation M. For the application of iterative decoding in MIMO system, we presented an iterative decoding/demodulation technique for an orthogonal space-time coded continuous-phase modulation system. By taking advantage of the orthogonal structure, the complexity of extrinsic information extraction can be significantly reduced at each iteration. We also investigated the concatenation of a low density generator matrix code as an outer encoder and a recursive space time trellis code as an inner coder to increase the system performance.

Available in PDF, EPUB and Kindle. Book excerpt: Space-time-frequency coded Multiple-Input and Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems have recently attracted much attention for broadband wireless communications including recent IEEE standards 802.11n and 802.16e. Space-time/Frequency Coding (SFC) can achieve the spatial and multipath diversities for a MIMO-OFDM system by coding across multiple antennas and subcarriers. In this research, we focus on a family of space-time-frequency codes proposed by Zhang et al to achieve both full spatial and multipath diversities by using Orthogonal Space-Time Block Codes (OSTBC). In particular, we develop a precoding algorithm for Peak-to-Average Power Ratio (PAPR) reduction and a clipping noise model based Maximum Likelihood (ML) decoding algorithm for Space-Time-Frequency Block Codes (STFBC) coded MIMO-OFDM systems. An important issue for OFDM systems is their high PAPR and it is important to reduce the PAPR in a practical (power efficient) system. The first goal of this research is to modify the repeating process and adjust phases of coded symbols so that the PAPR of the OFDM system is reduced. In particular, we propose to use Chu sequences for phase adjustment and show that the discrete PAPR can be reduced by & Gamma; times where & Gamma; is the times of the repeating across subcarriers. Another efficient way to reduce the PAPR in OFDM systems is clipping. After the clipping in an MIMO-OFDM system, the overall additive noise, including the clipping distortion, may not be white. The second goal of this research is to develop fast ML decoding algorithms for Orthogonal Space-Time-Frequency Block Codes (OSTFBC) and Quasi Orthogonal Space-Time-Frequency Block Codes (QOSTFBC) in clipped MIMO-OFDM systems. By using a clipping noise model with Gaussian approximation, our newly proposed fast ML decoding algorithms improve the system performance without increasing the decoding complexity. Simulation results are presented to illustrate the improvement. In order to apply the clipping noise model based ML decoding, the clipping ratio needs to be known at the receiver. We also consider the case when the clipping ratio is not known at the receiver. So a decision-aided clipping ratio estimation for MIMO-OFDM systems is proposed in our research, too. Except for MIMO-OFDM systems, in this work, cooperative OFDM system is investigated too. OFDM transmission has been proposed for cooperative communications to combat the time delays from the relay nodes, where the paths from relay nodes to destination node are treated as multipaths and space-time (or frequency) coding is used to achieve the spatial (or multipath) diversity. With this approach, when the Cyclic Prefix (CP) length is less than the time delay length, inter-block interference occurs. In this research, we consider Alamouti coded OFDM systems in cooperative communications where the CP length may be less than the time delay length. By taking the advantage of the Alamouti code structure, we propose a time domain interference cancellation algorithm.
