Design and Real-Time Implementation of a Baseband LPC Coder for Speech Transmission over 9600 BPS Noisy Channels. Volume II. Programming Listings.

Abstract

This report describes the design and development of a real-time baseband LPC speech coder that transmits high-quality speech over a 9600 bps synchronous channel with bit-error rates of up to 1%. Presented are the results of our investigation of a number of aspects of the baseband LPC coder with the goal of maximizing the quality of the transmitted speech. Important among these aspects are: baseband width, baseband coding, high-frequency regeneration, and error-protection of important transmission parameters. The report also includes the system design, detailed documentation, and program listings of the MAP-300 real-time implementation of the optimized speech coder. This report is bound in two volumes. Volume I contains the text of the report, and Volume II contains the program listings of the MAP-300 speech coder implementation. (Author)
