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.

Rutgers University launched WINLAB in 1989, just as the communications industry, the Federal government, and the financial community in the United States, were waking up to the growing public appetite for wireless communications and to the shortage of technology to feed it. The secret was already out in Europe, where no fewer than three new cordless and cellular systems were progressing from drawing board to laboratory to factory to consumers. In July 1989, the FCC held a well-attended tutorial that turned into a debate over whether second generation British or Swedish technology held the key to mass-market personal communications. Many in the audience wondered whether United States technology was out of the picture. Technology uncertainties are more acute in wireless communications than in any other information service. For example multi-gigabit optical fiber communications have followed an orderly progression from basic science leading to technology, which in turn stimulated standards, and then commercial products. Eventually applications will be found and industry and society at large will reap the benefits. By contrast, the applications of wireless communications are apparent to an eager public. A large market exists but is held in check by a shortage of capacity. The demand has led the cellular industry to formulate standards for advanced systems before the technology is in place to implement them. Everyone holds their breath waiting to observe performance of the first products. Gaps in basic science add to the uncertainty and forestall the resolution of technological debates.

In October 1993, the Rutgers University Wireless Infonnation Network Laboratory hosted the fourth WINLAB Workshop on Third Generation Wireless Infonnation Networks. These events bring together a select group of experts interested in the long tenn future of Personal Communications, Mobile Computing, and other services supported by wireless telecommunications technology. This is a fast moving field and we already see, in present practice, realizations of visions articulated in the earlier Workshops. In particular, the second generation systems that absorbed the attention of the first WINLAB Workshop, are now commercial products. It is an interesting reflection on the state of knowledge of wireless communications that the debates about the relative technical merits of these systems have not yet been resolved. Meanwhile, in the light of United States Government announcements in September 1993 the business and technical communities must confront this year a new generation of Personal Communications Services. Here we have applications in search of the best technologies rather than the reverse. This is a rare situation in the infonnation business. Today's advanced planning and forward looking studies will prevent technology shortages and uncertainties at the end of this decade. By then, market size and public expectations will surpass the capabilities of the systems of the mid-1990's. Third Generation Wireless Infonnation Networks will place greater burdens on technology than their predecessors by offering a wider range of services and a higher degree of service integration.

An important aspect of wireless networks is the deployment of their infrastructure. In this book, the Editors have invited a number of experts from industry to write on a variety of topics associated with deployment of digital wireless networks. The first part of the book consists of an overview of systems design and engineering integration, comparison of polarization and space diversity antenna systems, and the performance of deploying smart antenna architectures in cellular and PCS networks. The second part addresses deployment of CDMA networks, based on IS-95 standards. Here the authors discuss issues related to optimization of overlaid dual model CDMA networks, embedding microcells to improve hot-spot capacity, and mitigation of intermodulation distortion in handsets. Part III deals with deployment of TDMA- based networks. The issues presented include developing hierarchical systems, reconfigurable transceivers, and deploying the GSM frequency hopping feature for enhancing existing traffic capacity. The last part, on Wireless Data Networks, is comprised of issues related to the performance of GPRS systems deployed as an upgrade on current networks and deployment of wireless LANs. Critical issues for deploying an IEEE 802.11-based WLAN are examined. Wireless Network Deployments provides practical engineering guidance for wireless and cellular engineers, researchers, technicians, and managers working in second and third generation digital wireless networks.

The broadband wireless communications field is growing at an explosive rate, stimulated by a host of important emerging applications ranging from 3G, 4G and wireless LAN. Wideband CDMA and CDMA2000 will be used for 3G. OFDM+CDMA might be a good choice for 4G, CDMA overlay will possibly be used for new-generation broadband wireless LAN. For system planners and designers, the projections of rapidly escalating demand for such wireless services present major challenges and meeting these challenges will require sustained technical innovation on many fronts. The text of this book has been developed through years of research by the author and his graduate students at the University of Hong Kong. The aim of this book is to provide a R&D perspective on the field of broadband wireless communications by describing the recent research developments in this area and also by identifying key directions in which further research is needed. As a background, I presume that the reader has a thorough understanding of digital communications and spread spectrum/CDMA. The book is arranged into 13 chapters. In chapter 1, some key specifications of 3G WCDMA are described and discussed. These techniques include channel coding, rate matching, modulation and spreading, power control, cell search, transmit diversity, soft-handoff, and so son. In Chapter 2, the coherent RAKE reception of Wideband CDMA signals with complex spreading is considered. A dedicated pilot channel, which is separate from data channels, is used for the purpose of channel estimation.

This book is a collection of invited papers that were presented at the Ninth IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, September 5-8, 1998, Boston, MA. These papers are meant to provide a global view of the emerging third-generation wireless networks in the wake of the third millennium. Following the tradition of the PIMRC conferences, the papers are selected to strike a balance between the diverse interests of academia and industry by addressing issues of interest to the designers, manufacturers, and service providers involved in the wireless networking industry. The tradition of publishing a collection of the invited papers presented at the PIMRC started in PIMRC’97, Helsinki, Finland. There are two benefits to this tradition (1) it provides a shorter version of the proceedings of the conference that is more focused on a specific theme (2) the papers are comprehensive and are subject of a more careful review process to improve the contents as well as the presentation of the material, making it more appealing for archival as a reference book. The production costs of the book is subsidized by the conference and the editors have donated the royalty income of the book to the conference.
