VoIP Voice and Fax Signal Processing

A complete and systematic treatment of signal processing for VoIP voice and fax

This book presents a consolidated view and basic approach to signal processing for VoIP voice and fax solutions. It provides readers with complete coverage of the topic, from how things work in voice and fax modules, to signal processing aspects, implementation, and testing. Beginning with an overview of VoIP infrastructure, interfaces, and signals, the book systematically covers:

Voice compression

Packet loss concealment techniques

DTMF detection, generation, and rejection

Wideband voice modules operation

VoIP Voice-Network bit rate calculations

VoIP voice testing

Fax over IP and modem over IP

Country deviations of PSTN mapped to VoIP

VoIP on different processors and architectures

Generic VAD-CNG for waveform codecs

Echo cancellation

Caller ID features in VoIP

Packetization?RTP, RTCP, and jitter buffer

Clock sources for VoIP applications

Fax operation on PSTN, modulations, and fax messages

Fax over IP payload formats and bit rate calculations

Voice packets jitter with large data packets

VoIP voice quality

Over 100 questions and answers on voice and more than seventy questions and answers on fax are provided at the back of the book to reinforce the topics covered throughout the text. Additionally, several clarification, interpretation, and discussion sections are included in selected chapters to aide in readers' comprehension.

VoIP Voice and Fax Signal Processing is an indispensable resource for professional electrical engineers, voice and fax solution developers, product and deployment support teams, quality assurance and test engineers, and computer engineers. It also serves as a valuable textbook for graduate-level students in electrical engineering and computer engineering courses.

Excellent reference for VoIP fundamentals
This book is a complete reference of VoIP for both starters and for experienced. It covers almost everything you might need to understand VoIP from Digital Signal to IP Packet. Execellent Reference !



User review
Excellent reference, thorough treatment
This book provides detailed treatment of all aspect of VoIP technology from codec processing through network delivery. I found that this book works well both as a reference but also as a overview of technology. It covers a much broader range of topics than other books on the subject. For anyone working on VoIP technologies or interested in the area, this is a must read.


User review
One of the best books I have read in VOIP signal processing.
I have seen many books on VoIP, which provide the protocol aspects of VOIP/FOIP but none of them really dive into the signal processing aspects of it. This book is really written very well for the various signal processing aspects of VOIP technology.

One thing I liked very much is all the different terminologies, used in the VOIP industry, are explained so well that when the fresher or even the experienced engineer reads it he/she understands what it really means. It also provides minute details of every block of the VOIP/FOIP system with practical approach including QOS issues and testing, while the theoretical details are provided where ever needed. Third thing I like about this book is that it provides a Q&A section, which is very rare to see in these types of books. This section fills up any unanswered questions that comes in the readers mind after reading the book/section, it also serves as a quick reference.

In my opinion this book will serve as a very good practical signal processing system level reference book for everybody working (or studying) in the VOIP technology.
