Voice communications remains the most important facet of mobileradio services, which may be delivered over conventional fixedlinks, the Internet or wireless channels. This all-encompassingvolume reports on the entire 50-year history of voice compression,on recent audio compression techniques and the protection as wellas transmission of these signals in hostile wireless propagationenvironments.
Audio and Voice Compression for Wireless and WirelineCommunications, Second Edition is divided into four partswith Part I covering the basics, while Part II outlines the designof analysis-by-synthesis coding, including a 100-page chapter onvirtually all existing standardised speech codecs. The focusof Part III is on wideband and audio coding as well astransmission. Finally, Part IV concludes the book with a range ofvery low rate encoding techniques, scanning a range ofresearch-oriented topics.
* Fully updated and revised second edition of "VoiceCompression and Communications", expanded to cover Audiofeatures
* Includes two new chapters, on narrowband and wideband AMRcoding, and MPEG audio coding
* Addresses the new developments in the field of wideband speechand audio compression
* Covers compression, error resilience and error correctioncoding, as well as transmission aspects, including cutting-edgeturbo transceivers
* Presents both the historic and current view of speechcompression and communications.
Covering fundamental concepts in a non-mathematical way beforemoving to detailed discussions of theoretical principles, futureconcepts and solutions to various specific wireless voicecommunication problems, this book will appeal to both advancedreaders and those with a background knowledge of signal processingand communications.

Lajos Hanzo has been with the Department of Electronics andComputer Science, University of Southampton, UK, since 1986 wherehe holds the Chair in Telecommunications. He received his degree inelectronics in 1976 and his doctorate in 1983. During his career intelecommunications he has held various research and academic postsin Hungary, Germany and the UK. Lajos is a Fellow of the IEEE andthe IEE as well as an IEEE Distinguished Lecturer. He hasco-authored 11 books on mobile radio communications, published over500 research papers and been awarded a number of distinctions.
Clare Somerville received M.Eng and Ph.D degrees inElectronic Engineering in 1995 and 1999, respectively, from theUniversity of Southampton. From 1995 to 1998 she performed researchinto low bit rate speech coders for wireless communications.Following a spell of research with the Global Wireless SystemsResearch department, Bell Laboratories, Swindon, U.K, she moved toPicoChip in Bath, UK. Her current research involves real-timeservices over wireless networks with a packet air interface.
Jason Woodard received an MA in Physics from theUniversity of Oxford in 1991, then an MSc in Electronics and a PhDin Speech Coding from the University of Southampton in 1992 and1995 respectively. From 1995 to 1998 he worked as a Research Fellowat the University of Southampton, researching error correctioncoding, especially turbo codes. In 1998 he joined the WirelessTechnology Practice at PA Consulting Group in Cambridge. At thestart of 1999 he was transferred from PA to UbiNetics Ltd, where heis responsible for the development and implementation of bit rateprocessing algorithms, including turbo codes, for 3rd Generationmobile communications products.
