Abstract: Abstract of thesis entitled Multicarrier CDMA Overlay for Ultra-wideband Wireless Communications Submitted by Wong Tat Tung for the degree of Master of Philosophy at The University of Hong Kong in August 2003 Ultra-wideband (UWB) technology is widely considered to offer an innovative solution for future short-range high-speed wireless communications. In this study, the use of multi-carrier direct sequence code division multiple access (MC-DS-CDMA) overlay with both transmitter and receiver filtering is suggested for UWB applications, as an alternative to the conventional carrier-less approach. The main contribution of the study is to provide an analytical framework to illustrate the feasibility of the use of MC-DS- CDMA in UWB wireless communications. A literature review in Chapter 1 provides an overview of UWB technology and explains why MC-DS-CDMA is considered to be a feasible candidate for UWB communications. In Chapter 2, the factors of characterized large number multiple propagation paths and the existence of strong narrowband systems are taken into account for the construction of system model. Numerical expressions for performance evaluation are formulated and the system analysis is conducted with the assumption of random spreading code and Gaussian approximation. The performances of various receiving strategies are compared extensively. Results in Chapter 3 show that the proposed MC- DS-CDMA UWB system is capable of using spectrum already allocated to established services without causing noticeable interference to the existing users, and that pre- combining a minimum mean square error receiver with selective-maximal combining provides much better performance than a receiver made up of notch filter in cascade with code matched correlator or a code matched correlator receiver. A discussion of the significance of these results and conclusions are provided in Chapter 4 and Chapter 5 respectively.

Available in PDF, EPUB and Kindle. Book excerpt: Benefiting from both time-domain and frequency-domain signal processing techniques, multicarrier systems have the potential for achieving high spectral-efficiency, high-flexibility and low-complexity wireless communications. Multicarrier techniques therefore constitute the promising techniques for implementation of future generations of wideband, broadband and ultra-wideband systems. Multicarrier Communications offers comprehensive and in-depth evaluation of numerous topics in the area, covering the fundamental principles of spread-spectrum and multicarrier CDMA as well as more advanced topics such as multiuser detection (MUD), multiuser transmitter preprocessing (MUTP), MIMO and space-time processing. It examines OFDM and various multicarrier CDMA within an unified framework and provides analytical approaches and formulas for error-performance evaluation of numerous multicarrier systems. Examines MUD and MUTP in parallel to illustrate the strong duality between receiver optimization and transmitter optimization Comprehensively establishes the theory of noncoherent MUD and noncoherent interference suppression Details the body of knowledge on MIMO theory and space-time multicarrier communications Contains tables, diagrams and figures to illustrate the performance results. Practicing electrical engineers and researchers in wireless communications will find Multicarrier Communications an invaluable guide.

Book excerpt: asakta-buddhih sarvatra . jitatma vigata-sprhah . . . . naiskarmya-siddhim paramam . sannyasenadhigacchati Detached by spiritual intelligence from everything controlling the mind, without material desires, one attains the paramount perfection in cessation of re- tions by renunciation. The Bhagvad Gita (18.49) Compared to traditional carrier-based, Ultra-Wide Band (UWB), or carrier-less, systems implement new paradigms in terms of signal generation and reception. Thus, designing an UWB communication system requires the understanding of how excess bandwidth and very low transmitted powers can be used jointly to provide a reliable radio link. UWB offers systems transceiver potential for very simple implementations. Comparison between UWB and traditional narrow-band systems highlights the following features: Large bandwidth enables very fine time-space resolution for accurate lo- tion of the UWB nodes and for distributing network time stamps. Very short pulses are effectively counter-fighting the channel effect in very dense multipath environments. Data rate (number of pulses transmitted per bit) can be traded with power emission control and distance coverage. Very low power density leads to low probability of signal detection and adds security for all the layers of the communication stack. Very low power density is obtained through radio regulation emission masks; UWB systems are suitable for coexistence with already deployed narrow-band systems.

This book was released on 2006-07-06 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-carrier technologies have emerged as important instruments in telecommunications. OFDM is in the forefront, with its adoption by the IEEE 802.11 standards committee and the European HYPERLAN standards group. Following OFDM, MC-CDMA is also demonstrating considerable promise when compared to competing technologies. According to the authors, these technologies are just the beginning in the coming multi-carrier revolution. In Multi-Carrier Technologies for Wireless Communication, the authors explain how a common multi-carrier platform is being designed for DS-CDMA, TDMA, OFDM and MC-CDMA systems. Findings are presented which show how this multi-carrier platform enhances network capacity and probability of error performance.Specific results include (1) innovation in multi-carrier technologies that are enabling them to become an integral part of TDMA and DS-CDMA systems; and (2) the design of multi-carrier systems to overcome PAPR problems (in, e.g., OFDM). Multi-Carrier Technologies for Wireless Communication is an important book for engineers who work with DS-CDMA, TDMA, OFDM, or MC-CDMA systems, and are seeking new ways of exploiting the wireless medium based on a "smarter" signal processing.

Available in PDF, EPUB and Kindle. Book excerpt: Frequency spectrum is a limited and valuable resource for wireless communications. A good example can be observed among network operators in Europe for the prices to pay for UMTS-frequency bands. Therefore, the first goal when designing future wireless communication systems (e.g. 4G - fourth generation) has to be the increase in spectral efficiency. The development in digital communications in the past years has enabled efficient modulation and coding techniques for robust and spectral efficient data, speech, audio and video transmission. These are the multi-carrier modulation (e.g. OFDM) and the spread spectrum technique (e.g. DS-CDMA), where OFDM was chosen for broadcast applications (DVB, DAB) as well as for broadband wireless indoor standards (ETSI HIPERLAN-II, IEEE-802.11) and the DS-CDMA was selected in mobile communications (IS-95, third generation mobile radio systems world wide, UMTS/IMT 2000). Since 1993 various combinations of multi-carrier (MC) modulation and the spread spectrum (SS) technique have been introduced and the field of MC-SS communications has become an independent and important research topic with increasing activities. New application fields have been proposed such as high rate cellular mobile, high rate wireless indoor and LMDS. It has been shown that MC-SS offers the high spectral efficiency, robustness and flexibility that is required for the next generation systems. Meanwhile, different alternative hybrid schemes such as OFDM/OFDMA, MC-TDMA, etc. have been deeply analysed and adopted in different international standards (ETSI-BRAN, IEEE-802 & MMAC). Multi-Carrier & Spread-Spectrum: Analysis of Hybrid Air Interfaces draws together all of the above mentioned hybrid schemes therefore providing a greatly needed resource for system engineers, telecommunication designers and researchers in order to enable them to develop, build and deploy several schemes based on MC-transmission for the next generation systems (which will be an integration of broadband multimedia services covering both 4G mobile and fixed wireless systems). * Offers a complete treatment of multi-carrier, spread-spectrum (SS) and time division multiplexing (TDM) techniques * Provides an in-depth insight into hybrid multiple access techniques based on multi-carrier (MC) transmission * Presents numerous hybrid multiple access and air interface architectures including OFDM/CDMA, MC-CDMA, MC-DS-CDMA and MT-CDMA * Covers new techniques such as space-time coding and software radio Telecommunications engineers, hardware & software system designers and researchers as well as students, lecturers and technicians will all find this an invaluable addition to their bookshelf.
