Items related to Voice Compression and Communications
Synopsis
In the era of third-generation (3G) wireless personal communications standards - despite the emergence of broadband access network standard proposals, the most important mobile radio services are still based on voice communications. Even when the predicted surge of wireless data and Internet services becomes a reality, voice remains the most natural means of human communication, although this may be delivered via the Internet, predominantly after compression. Voice Compression and Communications is dedicated to voice compression issues while covering the aspects of error resilience, coding delay, implementation complexity and bitrate, characterizing many different speech codes incorporated in source-sensitivity matched wireless transceivers. Following the overview of the recent history of speech compression and communications, the book provides the reader with an historical perspective, commencing with a rudimentary introduction to communications aspects, since the expected performance of various speech codes are studied in the context of a full wireless transceiver.

From the Back Cover
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.
