Voice and audio compression for wireless communications Voice communications remains the most important facet of mobile radio services which may be delivered over conventional fixed links the Internet or wireless channels. This all encompassing volume reports on the entire 50 year history of voice compression on recent audio compression techniques and the protection as well as transmission of these signals in hostile wireless propagation environments. Audio and Voice Compression for Wireless and Wireline Communications Second Edition is divided into four parts with Part I covering the basics while Part II outlines the design of analysis by synthesis coding including a 100 page chapter on virtually all existing standardised speech codecs. The focus of Part III is on wideband and audio coding as well as transmission. Finally Part IV concludes the book with a range of very low rate encoding techniques scanning a range of research oriented topics. . Fully updated and revised second edition of “Voice Compression and Communications” expanded to cover Audio features. Includes two new chapters on narrowband and wideband AMR coding and MPEG audio coding. Addresses the new developments in the field of wideband speech and audio compression. Covers compression error resilience and error correction coding as well as transmission aspects including cutting edge turbo transceivers. Presents both the historic and current view of speech compression and communications. Covering fundamental concepts in a non mathematical way before moving to detailed discussions of theoretical principles future concepts and solutions to various specific wireless voice communication problems this book will appeal to both advanced readers and those with a background knowledge of signal processing and communications About the Authors Other Wiley and IEEE Press Books on Related Topics Preface and Motivation Acknowledgements I Speech Signals andWaveform Coding 2 Predictive Coding 3 Analysis by synthesis Principles 4 Speech Spectral Quantization 5 RPE Coding 6 Forward Adaptive CELP Coding 7 Standard CELP Codecs 8 Backward Adaptive CELP Coding 9 Wideband Speech Coding 10 MPEG 4 Audio Compression and Transmission 11 Overview of Low rate Speech Coding 12 Linear Predictive Vocoder 13 Wavelets and Pitch Detection 14 Zinc Function Excitation 15 Mixed Multiband Excitation 16 Sinusoidal Transform Coding Below 4kbps 17 Conclusions on Low Rate Coding 18 Comparison of Speech Transceivers 19 Voice Over the Internet Protocol A Constructing the Quadratic Spline Wavelets B Zinc Function Excitation C Probability Density Function for Amplitudes Bibliography Index Author Index
