System aspects of digital mobile earth stations

This Supplement provides characteristics of a digital voice-grade mobile earth station and a low G/T mobile earth station. Detailed description is also provided for an example of forward error control (FEC) for multi-path fading compensation and enhanced group call system. In § 4.2 and 4.5 of the original MSS Handbook, general explanation was presented for the basic of MSS system engineering. This Supplement is intended to provide the design principles of currently used digital MSS systems together with practical design examples.
