PROCEDURES AND EQUIPMENT FOR IMPROVING THE STRENGTHENING PLACE IN LEGAL TRANSFERS

摘要

Circuitry for a communication device, comprising: an input (54) for receiving a digitized bit stream, an output (66) for outputting an encoded bit stream, a first vocoder portion (150) for encoding the digitized bit stream at a first data rate to generate a first encoded bit stream; a second vocoder portion (154) for encoding the digitized bit stream at a second data rate to generate a second encoded bit stream; a selector (174) connected to said first and second vocoder portion (150, 154) and having a control input for receiving a control signal (70), for increasing the link margin of a transmission by selecting the vocoder portion (150; 154) which is outputting a lower bit stream rate.
