Speech and Audio Coding for Wireless and Network Applications contains 34 chapters, loosely grouped into six topical areas. The chapters in this volume reflect the progress and present the state of the art in low-bit-rate speech coding, primarily at bit rates from 2.4 kbit/s to 16 kbit/s. Together they represent important contributions from leading researchers in the speech coding community. Speech and Audio Coding for Wireless and Network Applications contains contributions describing technologies that are under consideration as standards for such applications as digital cellular communications (the half-rate American and European coding standards). A brief Introduction is followed by a section dedicated to low-delay speech coding, a research direction which emerged as a result of the CCITT requirement for a universal low-delay 16 kbit/s speech coding technology and now continues with the objective of achieving toll quality with moderate delay at a rate of 8 kbit/s. A section on the important topic of speech quality evaluation is then presented. This is followed by a section on speech coding for wireless transmission, and a section on audio coding which covers not only 7 kHz bandwidth speech, but also wideband coding applicable to high fidelity music. The book concludes with a section on speech coding for noisy transmission channels, followed by a section addressing future research directions. Speech and Audio Coding for Wireless and Network Applications presents a cross-section of the key contributions in speech and audio coding which have emerged recently. For this reason, the book is a valuable reference for all researchers and graduate students in the speech coding community.

The success of first and second generation wireless systems has paved the way for further research opportunities towards the next generation systems. The two standards GSM and IS-95 based on TDMA and CDMA respectively, have deeply influenced our system-level understanding, bringing new perspectives on the problems associated with wireless networks and potential for innovations. This volume presents the proceedings of the second workshop on multiaccess, mobility and teletraffic for personal communications held in May 1996 in Paris, France where some important subjects on the next generation systems have been treated. These include topics dealing with information theoretic aspects, channel modeling, diversity, interference control, resource allocation, power control, packet multi-access, stochastic modeling of mobility and traffic, and wireless network control. The selected topics in this workshop and their presented set of solutions reflect the richness of the problems in wireless communications. Indeed, development of theoretical frameworks with considerable attention to the peculiar environment of wireless communications has been the prime objective of this workshop. To elaborate, consider the problem of multi-access methods which remains a challenge for researchers. A complete evaluation of an access scheme must consider different aspects such as propagation, interference, mobility and traffic modeling. Some common bases, paradigms and models are needed. For example, today, we do not have a common archetype like the A WGN channel as in classical statistical communication. Clearly, there is a need for justified assumptions and models.

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.

Software defined radio (SDR) is one of the most important topics of research, and indeed development, in the area of mobile and personal communication. SDR is viewed as an enabler of global roaming and as a unique platform for the rapid introduction of new services into existing live networks. It therefore promises mobile communication networks a major increase in flexibility and capability. SDR brings together two key technologies of the last decade - digital radio and downloadable software. It encompasses not only reconfiguration of the air interface parameters of handset and basestation products but also the whole mobile network, to facilitate the dynamic introduction of new functionality and mass-customised applications to the user's terminal,post-purchase.

In particular it explores

• the unique demands of SDR upon the RF subsystem and their implications for front end design methodologies

• the recent concepts of the 'digital front end' and 'parametrization'

• the role and key influence of data conversion technologies and devices within software radio, essential to robust product design

• the evolution of signal processing technologies, describing new architectural approaches

• management of terminal reconfiguration and its network implications

• the concepts of the waveform description language

• potential breakthrough technologies, such as superconducting RSFQ technology and the possible future role of MEMS in RF circuitry

• competing approaches, eg all-software radios implemented on commodity computing vs advanced processing architectures that dynamically optimise their configuration to match the algorithm requirements at a point in time

Contributed by internationally respected industry practitioners and researchers this book provides a holistic treatement of SDR addressing the full breadth of relevant technologies - radio frequqncy design, data conversion, reconfigurable signal processing hardware, and software issues at all levelsof the protocol stack and network. As such it provides a solid grounding for a new generation of wireless engineers for whom radio design in the future will assume dynamic flexibility as a given.
