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.
