A complete and systematic treatment of signal processing for Vo IP
voice and fax
This book presents a consolidated view and basic approach to
signal processing for Vo IP 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 Vo IP
infrastructure, interfaces, and signals, the book systematically
covers:
* Voice compression
* Packet loss concealment techniques
* DTMF detection, generation, and rejection
* Wideband voice modules operation
* Vo IP Voice-Network bit rate calculations
* Vo IP voice testing
* Fax over IP and modem over IP
* Country deviations of PSTN mapped to Vo IP
* Vo IP on different processors and architectures
* Generic VAD-CNG for waveform codecs
* Echo cancellation
* Caller ID features in Vo IP
* Packetization–RTP, RTCP, and jitter buffer
* Clock sources for Vo IP 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
* Vo IP 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.
Vo IP 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.
