CDMA: Access and Switching addresses two unique uses of CDMA. The first is its use as a generalized method for multiple access communications and the second is its use in switching applications. Hence, the concepts introduced will enable readers to understand that multi-user communications (whether access or switching) can be presented as generalized code division networks. Each new application presented is assessed and evaluated while each innovative design is followed by rigorous performed analysis.

• Introduces the concepts of generalized CDMA and code division switching and analyzes spreading sequences for orthogonal, quasi-orthogonal and pseudo-orthogonal access systems
• Presents the Satelite Switched CDMA (SS/CDMA) as a system application and evaluates its end-to-end BER performance and throughput
• Features methods and procedures for random access, synchronization and carrier demodulation in CDMA networks and examines the CDMA performance under non-linear amplification
• Discusses methods of adaptive power control and multi-user detection in asynchronous CDMA networks

A cognitive radio is a transceiver which is aware of its environment, its own technical capabilities and limitations, and those of the radios with which it may communicate; is capable of acting on that awareness and past experience to configure itself in a way that optimizes its performance; and is capable of learning from experience. In a real sense, a cognitive radio is an intelligent communications system that designs and redesigns itself in real time. Cognitive Radio Engineering is both a text and a reference book about cognitive radio architecture and implementation, intended for readers who want to design and build working cognitive radios. It takes the reader from conceptual block diagrams through the design and evaluation of illustrative prototypes. An important goal is to bridge the divide between radio engineers, who often have little experience with the computational resource and timing issues inherent in cognitive radios, and computer engineers who often are unaware of RF issues like dynamic range, intermodulation products, and acquisition time. Following a brief overview of cognitive radio history and a high-level look at cognitive radio operation, the book presents a detailed study of cognitive engine design and analysis. After treating RF subsystems the book considers computational platforms and computation issues in cognitive radios, followed by system integration, evaluation methods for cognitive radio, and cognitive radio design for networking. The book concludes with coverage of cognitive radio applications in communications.

The operation frequencies, bandwidths and data capacities of communications systems are continuously increasing by employing advanced technologies and aggressive scaling of device dimensions. However, the restrictions inherent in scaling make the design of radio frequency integrated circuits a demanding task. To meet the corresponding challenges designers must provide profound skills in several areas including circuit theory, silicon and compound semiconductor technologies, communications standards, system design, measurement techniques, etc. The book aims at addressing all these multidisciplinary issues in a compact and comprehensive form and in a single volume. Suitable for students, engineers and scientists, the manuscript offers the necessary theoretical background together with cookbook-like optimisation strategies and state-of-the-art design examples.

"Well informed people know it is impossible to transmit the voice over wires, and that were it possible to do so, the thing would be ofno practical value. " from an editorial in the Boston Post -1865 Fortunately for the telecommunications industry, the unknown author of the above statement turned out to be very mistaken indeed. Even as he spoke, Alexander Graham Bell was achieving the impossible, with a host of competing inventors close behind. The communications revolution which ensued has changed the way in which we live and work, and the way in which we view the world around us. Wired telephone lines now encircle the globe, allowing instantaneous transmission of voice and data. Events from Times Square to Red Square are now as accessible as events on the local courthouse lawn. The advent of wireless communications has extended Bell's revolution to another domain. Personal communications promises voice, data and images which are accessible everywhere. Although predictions are dangerous, a look back over the last decade reveals spectacular growth. In the United States alone, there are now over 50 million cordless phones in use throughout the country -at least one cordless phone for every 3 households - and nearly 20 million pocket pagers. U. S. Cellular telephone service, launched commercially in 1984, has experienced 30-40% annual growth rates despite a sluggish economy.

Personal and Wireless Communications: Digital Technology and Standards is devoted to providing a concise explanation of the newly emerging wireless access standards for Personal Communications Services (PCS). PCS is a new concept which will expand the horizon of wireless communications beyond the limitations of current cellular systems to provide end users with the ability to communicate with anyone, anywhere, anytime'. Because of the inherent nature of mobility, which is characteristic of personal communications, wireless communications and PCS have become inseparable concepts. In particular, PCS will critically depend on wireless technologies for the mobile-to-network access portion of the service, which is referred to as the common air interface. The topic of this book is the wireless access technology used for the common air interface in order to support PCS. Personal and Wireless Communications: Digital Technology and Standards presents clear tutorial expositions of the main digital technology elements employed for wireless access systems. The main objective is to pull together in one place all the important basic technical elements necessary in understanding wireless access systems, so that the reader can obtain an overall view of the technology quickly and systematically. The book also reviews the common air interface standards for PCS, and in doing so has two main objectives. The first is to sift out and summarize important elements of the standards, which are buried in the veritable mountain of paper comprising the standards literature, in all too many unfamiliar terms, notations, and abbreviations. The second objective is to expand, almost paradoxically, some of the more important elements to explain the intent and significance of the written words of the standards. Personal and Wireless Communications: Digital Technology and Standards will provide a quick means of obtaining a comprehensive picture of overall aspects which are important in the area. This book will be useful as a text for an advanced course on the subject.
