This book was released on 2010-10 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital modulation techniques are basic building blocks of the physical or radio interface of all digital communication systems. In a digital communication system with a wireless link, the channel effects can heavily degrade the system performance since the wireless link is time-varying and may experience multipath fading and interference. This book gives the idea about three major types of modulation techniques, namely QPSK, MSK, and 16-QAM, applied to additive white Gaussian noise (AWGN) channel and Rayleigh fading channel and tries to find out the performance of these modulation schemes using forth-generation numerical computing environment, MATLAB. The book is targeted to the academic students as well as researchers and would help them to understand the performance degradation of digitally modulated signals due to Rayleigh fading channel with respect to that of an AWGN channel.

Available in PDF, EPUB and Kindle. Book excerpt: A unified presentation, broad coverage, single-volume convenience This timesaving reference provides a unified approach to the performance analysis of digital communication systems over generalized fading channels. Employing alternative forms of such classical mathematical functions as the Gaussian Q-function, the Marcum Q-function, and the incomplete Gamma function, the book expresses communication system error probability performance in terms of the moment generation function (MGF) of the fading process. This MGF-based approach provides the unifying backbone of the book. Digital Communication over Fading Channels discusses in detail coherent, differentially coherent, and noncoherent communication systems as well as a large variety of fading channel models typical of communication links found in the real world. Coverage also includes single- and multichannel reception and, in the case of the latter, a large variety of diversity types. For each combination of communication type, channel fading model, and diversity type, the average bit error rate and/or symbol error rate is expressed in an easy-to-evaluate form. Special features include: * Important results previously scattered over many publications-now in a single volume * Simplified results heretofore available only in complex forms * Extremely broad coverage of topics * Explores practical applications, including the problem of optimum combining in the presence of co-channel interference

Download or read book Performance Analysis of Efficient Receivers and Modulation Techniques for Digital Communication Systems written by Redha Mahmoud Radaydeh and published by . This book was released on 2006 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dissertation analyzes the performance of efficient receivers and modulation techniques for multiple and single user digital communications systems. It is partitioned into four main parts. In the first part, the average error performance of direct sequence code division multiple access (DS-CDMA) employing noncoherent orthogonal modulation in the presence of additive white Gaussian noise (AWGN) and partial-band interference (PBI) is analyzed over generalized fading channels. The noncoherent equal-gain combining (NC-EGC) (which is also known as the square-law combining) is used to achieve diversity gain. New generalized results for the system average error performance are derived for the cases of independent identically distributed (i.i.d), independent nonidentically distributed (i.n.d), and arbitrarily correlated diversity branches. The analysis considers four channel fading models; Rayleigh, Nakagami- m, Rician, and Nakagami- q distributions. These channel fading distributions are widely used to describe multipath small scale fading in real mobile and satellite radio links. The second part of the dissertation proposes designs for noncoherent and differentially-coherent diversity receivers to mitigate the disadvantages of the conventional square-law receiver over nonidentically distributed Nakagami- m, Rician, and Nakagami- q fading channels. It is shown that the proposed diversity receivers result in simple expressions for the average error performance, and achieve performance improvements over that of the conventional square-law receiver for both cases of independent and arbitrarily correlated diversity branches. The third part presents a new design for noncoherent modulation technique based on combining power-efficient noncoherent orthogonal multilevel frequency-modulated signals and bandwidth-efficient multilevel polarization-modulated signals. The analysis considers the wireline optical communication links, and it shows that the proposed modulation scheme achieves simultaneous improvements in the power and bandwidth efficiencies with low detection complexity by maintaining the noncoherent detection property at the receiver side. The final part of the dissertation presents new results for the average of higher-order powers of the one-dimensional Gaussian Q -function over Rayleigh and Nakagami- m fading channels employing linear diversity combining. Expressions are newly derived for i.i.d and i.n.d fading scenarios. The derived results are useful for several applications in the wireless communication theory, especially in evaluating the average error performance of various uncoded and coded communication systems over multi-branch fading channels.

Available in PDF, EPUB and Kindle. Book excerpt: In order to adapt to the ever-increasing demands of telecommunication needs, today’s network operators are implementing 100 Gb/s per dense wavelength division multiplexing (DWDM) channel transmission. At those data rates, the performance of fiberoptic communication systems is degraded significantly due to intra- and inter-channel fiber nonlinearities, polarization-mode dispersion (PMD), and chromatic dispersion. In order to deal with those channel impairments, novel advanced techniques in modulation and detection, coding and signal processing are needed. This unique book represents a coherent and comprehensive introduction to the fundamentals of optical communications, signal processing and coding for optical channels. It is the first to integrate the fundamentals of coding theory with the fundamentals of optical communication.

This book was released on 2012-12-06 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coded-Modulation Techniques for Fading Channels provides the reader with a sound background for the application of bandwidth-efficient coded-modulation techniques in fading channels. The book systematically presents recent developments in the field, which has grown rapidly in recent years, and provides a solid frame of reference for further research in this area. During the past decade there has been a proliferation of research in the area of bandwidth-efficient coded-modulation techniques. The primary advantage of these schemes over modulation schemes employing traditional error correcting codes is their ability to improve the performance of the communication system without bandwidth expansion. This property makes them a suitable choice for channels which are limited in both power and bandwidth. A typical example of such channels is a mobile satellite channel, where it is desired to accommodate a large number of users in a given bandwidth with a power which is constrained by the physical size of the satellite and by the vehicle's antenna. Coded-Modulation Techniques for Fading Channels is an excellent reference for researchers and practicing engineers, and may be used as a text for advanced courses on the subject.

Download or read book Synchronization Techniques for Digital Receivers written by Umberto Mengali and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synchronization is a critical function in digital communications; its failures may have catastrophic effects on the transmission system performance. Furthermore, synchronization circuits comprehend such a large part of the receiver hardware that their implementation has a substantial impact on the overall costs. For these reasons design engineers are particularly concerned with the development of new and more efficient synchronization structures. Unfortunately, the advent of digital VLSI technology has radically affected modem design rules, to a point that most analog techniques employed so far have become totally obsolete. Although digital synchronization methods are well established by now in the literature, they only appear in the form of technical papers, often concentrating on specific performance or implementation issues. As a consequence they are hardly useful to give a unified view of an otherwise seemingly heterogeneous field. It is widely recognized that a fundamental understanding of digital synchronization can only be reached by providing the designer with a solid theoretical framework, or else he will not know where to adjust his methods when he attempts to apply them to new situations. The task of the present book is just to develop such a framework.
