Voice Circuit Multiplier Techniques-A Comparison Study for Satellite Systems

摘要

Voice circuit multiplier techniques which increases the capacity of satellites per unit bandwidth (voice channels per MHz) are described and their performance attributes identified. Companding, TASI, overdeviation, digital voice encoding and advanced digital modulation techniques are included. FDM/FM and TDMA/DSI baseline system configurations are developed and comparisons of various voice circuit multipliers are given.
