摘要：
Stojce Dimov Ilcev of Mangosuthu University of Technology in Durban, South Africa, reviews the basic and the latest channel coding, decoding, and error correction techniques, along with channel processing used in Mobile Satellite Communications. The system for digital speech concentration uses the activity factor of telephone channels to reduce the number of satellite channels required to transmit a given number of terrestrial channels. Several users can be permitted to share the same telephone circuit by making use of the actual activity of the channels and techniques for data and video signals. The effective data transfer through the Inmarsat MSC system can be significantly increased by using data compression software.
