This book was released on 2005-12-21 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space-Time Processing for CDMA Mobile Communications is one of the first books to: bring together spatial/temporal channel models and analytic performance evaluation techniques; establish a link between smart antenna systems and advanced receiver design techniques; treat smart antennas specifically for UMTS-like communication systems, with applicable simulations and calculations; supply code with Matlab® GUI so readers can run or modify existing simulations or create new ones. The field of smart antenna technology or, more generally, space-time processing is rapidly becoming one of the most promising areas of mobile communications, especially regarding the development of the first practical third-generation mobile communication systems. The authors have addressed many of the most basic questions relating to the use of space-time processing in CDMA-based third-generation systems and have presented models for the integration of space-time processing, error correction coding, and multi-user detection techniques. Included is extensive background information on cellular systems, antenna array theory, smart antenna techniques, performance of basic space-time processors and advanced space-time processors. The book also includes an extensive simulation program written in Matlab®. The simulation code implements both the uplink and the downlink of a UMTS-like communication system. This provides multiple options for simulating system performance using a variety of channel models as well as receiver structures. Space-Time Processing for CDMA Mobile Communications will be an invaluable reference work for engineers and researchers, and a useful source for design engineers enabling them to understand the implications of adding space-time processing systems to CDMA-based communication systems.

Available in PDF, EPUB and Kindle. Book excerpt: As the growing demand for mobile communications is constantly increasing, the need for better coverage, improved capacity, and higher transmission quality rises. Thus, a more efficient use of the radio spectrum is required. Smart antenna systems are capable of efficiently utilizing the radio spectrum and is a promise for an effective solution to the present wireless systems’ problems while achieving reliable and robust high-speed high-data-rate transmission. The purpose of this book is to provide the reader a broad view of the system aspects of smart antennas. In fact, smart antenna systems comprise several critical areas such as individual antenna array design, signal processing algorithms, space-time processing, wireless channel modeling and coding, and network performance. In this book we include an overview of smart antenna concepts, introduce some of the areas that impact smart antennas, and examine the influence of interaction and integration of these areas to Mobile Ad-Hoc Networks. In addition, the general principles and major benefits of using space-time processing are introduced, especially employing multiple-input multiple-output (MIMO) techniques.

This book was released on 2006-04-18 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: During 12-15 of September 1999, 10th International Symposium on P- sonal, Indoor and Mobile Radio Communications (PIMRC’99) was held in Osaka Japan, and it was really a successful symposium that accommodated more than 600 participants from more than 30 countries and regions. PIMRC is really well organized annual symposium for wireless multimedia commu- cation systems, in which, various up-to-date topics are discussed in the invited talk, panel discussions and tutorial sessions. One of the unique features of the PIMRC is that PIMRC is continuing to publish, from Kluwer Academic Publishers since 1997, a book that collects the hottest topics discussed in PIMRC. In PIMRC’97, Invited talks were sum- rized in “Wireless Communications –TDMA versus CDMA – (ISBN 0-7923- 8005-3),” and it was published just beforePIMRC’97. This book was also distributed to all the PIMRC’97 participants as a part of proceedings for the conference. In PIMRC’98, extendedversion of the invited papers were s- marized in Wireless Multimedia Network Technologies (ISBN 0-7923-8633- 7) and published in September 1999, which is almost the same timing for the PIMRC’99. In the case of PIMRC’99, to produce more informative book, we have - lected topics that attracted many PIMRC’99 participants during the conf- ence, and invited prospective authors not only from the invited speakers but also from tutorial speakers, panel organizers, panelists, and some other exc- lent PIMRC’99 participants.

Research has generated a number of solutions for significant improvement of system performance. The development of enabling technologies such as adaptive coding and modulation, iterative (turbo) decoding algorithms and space-time coding, means that industry can now implement these solutions. Advanced Wireless Communications: 4G Technologies focuses on the system elements that provide adaptability and reconfigurability and discusses how these features can improve 4G system performance. There are several different systems comprising 4G, including adaptive WCDMA (Wideband Code Division Multiple Access), ATDMA (Adaptive Time Division Multiple Access), Multicarrier (OFDMA) and Ultra Wide Band (UWB) receiver elements. This book provides a comparative study of these technologies and focuses on their future co-existence. Topics covered include: Space Time Coding, including discussions on diversity gain, the encoding and transmission sequence, the combining s cheme and ML decision rule for two-branch transmit diversity scheme with one and M receivers. Ultra Wide Band Radio, UWB multiple access in Gaussian channels, the UWB channel, UWB system with M-ary modulation, M-ary PPM UWB multiple access, coded UWB schemes, multi-user detection in UWB radio, UWB with space time processing and beam forming for UWB radio. Antenna array signal processing with focus on Space-Time receivers for CDMA communications, MUSIC and ESPRIT DOA estimation, joint array combining and MLSE receivers, joint combiner and channel response estimation and complexity reduction in the wide-band beam forming Channel modeling and measurement, adaptive MAC, adaptive routing and TCP layer are also addressed. This book will supply the reader with a comprehensive understanding of the relationship between the systems performance, its complexity/reliability and cost-effectiveness.

This book was released on 2004-10-01 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unprecedented growth in the range of multimedia services offered these days by modern telecommunication systems has been made possible only because of the advancements in signal processing technologies and algorithms. In the area of telecommunications, application of signal processing allows for new generations of systems to achieve performance close to theoretical limits, while in the area of multimedia, signal processing the underlying technology making possible realization of such applications that not so long ago were considered just a science fiction or were not even dreamed about. We all learnt to adopt those achievements very quickly, but often the research enabling their introduction takes many years and a lot of efforts. This book presents a group of invited contributions, some of which have been based on the papers presented at the International Symposium on DSP for Communication Systems held in Coolangatta on the Gold Coast, Australia, in December 2003. Part 1 of the book deals with applications of signal processing to transform what we hear or see to the form that is most suitable for transmission or storage for a future retrieval. The first three chapters in this part are devoted to processing of speech and other audio signals. The next two chapters consider image coding and compression, while the last chapter of this part describes classification of video sequences in the MPEG domain.

Available in PDF, EPUB and Kindle. Book excerpt: Antenna arrays have shown great promise for improving performance in wireless communication and radar systems. In this dissertation, new approaches and design algorithms are suggested for producing antenna array signal processing schemes that achieve improved performance. First, a modified space-time adaptive processing (STAP) scheme is proposed for airborne radar signal detection. A simple model for ground clutter is used to aid the estimation of the covariance matrix in a nonhomogeneous environment. The resulting algorithm provides good performance without much training data. Next, distributed detection of a known signal in t-distributed noise is studied for cases where the observations are correlated from sensor to sensor. A Gauss-Seidel algorithm which attempts to minimize the Bayes risk is used to obtain the optimum decision rules. It is shown that the optimum sensor decision rules can be predicted in a simple way based on the problem's parameters. Finally the exploitation of transmit diversity and receive diversity in wireless communications is considered by using space-time codes. Systematic code search procedures with low complexity are proposed for space-time codes employing multiple trellis coded modulation (MTCM). MTCM is shown to be necessary for achieving maximum transmit diversity gain when trellis codes with parallel paths are used. By properly labeling the trellis branches, it is demonstrated that the overall coding gain can be made larger than that achieved by conventional space-time codes with the same throughput and the same number of states. A new family of space-time codes is proposed using a serial concatenation structure. An interleaver is embedded between the inner code and the outer code. Analysis shows that by using this structure, both diversity gain and interleaving gain can be achieved for system performance improvement.

This book was released on 2012-08-23 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: So far there does not exist any theory of adaptive spatial signal processing (ASSP) for signals with uncertain parameters. This monograph is devoted to the development of this theory, which is very important in connection with wide spreading of telecommunications and radio links in the modern society. This theory can be applied for the development of effective radio communications. In the book some original approaches are proposed targeting the development of effective algorithms of ASSP with not exactly known parameters. They include both probabilistic and deterministic approaches for synthesis of robust algorithms of ASSP. The solution of problems also can be reduced to the construction of some operators for the Banach space which is presented in the book. “Methods of Signal Processing for Adaptive Antenna Arrays” targets professionals, students and PhD students in the area of telecommunications and should be useful for everybody connected with the new information technologies.
