Abstract

A source/channel encoding mode control method in a TDMA radio communication system determines the current type of source signal to be encoded and transmitted, restricts encoding to a class of source/channel encoding modes compatible with the determined type of source signal, determines a quality measure for previously transmitted signals that have been received and decoded, and selects based on the quality measure, the most suitable source/channel encoding mode for the determined class.
