Voice Compression and Communications: Principles and Applications for Fixed and Wireless Channels

ISBN: 978-0-471-15039-8
672 pages
September 2001, Wiley-IEEE Press
Voice Compression and Communications: Principles and Applications for Fixed and Wireless Channels (0471150398) cover image
Up-to-date, expert coverage of topics in wireless voice communications
Voice communication is the most important facet of mobile radio service. Even when the predicted surge of wireless data and Internet services becomes a reality, voice will remain the most natural means of human communication.
Voice Compression and Communications details issues in wireless voice communications and treats compression, channel coding, and wireless transmission as a joint subject. Part I covers background material, whereas Part II provides detailed information on both proprietary and standardized analysis-by-synthesis codecs, including the speech codecs of virtually all existing wireline-based and wireless systems. Parts III and IV discuss mainly research-based wideband, audio, as well as very low-rate schemes likely to find their way into future standards.
Voice Compression and Communications describes fundamental concepts in a non-mathematical way early in the book for those with only a background knowledge of signal processing and communications. More advanced readers will find detailed discussions of theoretical principles, future concepts, and solutions to various specific wireless voice communications problems.
