Abstract
A mobile radio system enables exchange of bidirectional digital signals between at least one mobile station and at least one base transceiver station and provides at least two coding modes, each mode corresponding to a predetermined source code and a predetermined channel code for the transmission of a wanted signal for each transmission direction. Each source code corresponds to a given user bit rate and each channel code corresponds to a given coding efficiency and therefore to a given total bit rate for a given source code. For adaptation of the air interface of this system, at the time of a call between a mobile station and a base transceiver station, two separate analyses of transmission quality are carried out for each transmission direction, respectively, and, for each transmission direction, one of the coding modes is selected in accordance with the corresponding transmission quality analysis.
