A Speech Encoder-Multiplexer Feasibility Study.
Abstract
The report contains a detailed study of various voice differential PCM systems applicable for digitally encoding 3, 4, 5 and 6 voice channels into a 153.6 kilobit per second digital signal which can be used in a switched telecommunication network. Transmission of both speech and data signals over these voice channels is considered. Included in the report are: Calculations of the performance of differential PCM systems with various data signals; An analysis of the performance of differential PCM systems with speech signals; A description of a differential PCM system constructed using standard T1 technology. The research reported here consists of theoretical studies, computer simulation, subjective testing and hardware construction. (Author)
