<p>A multi-channel transcoder (800) with rate adapter converts the data rate of GSM and PSTN network data in a multi-channel network. A transcoder (800) having echo-cancellation (809) features uses the robust voice activity detection (810) and comfort noise booster (811) functions of the GSM transcoder functions to enhance the accuracy of echo-cancellation of near-end signals (805, 806). A method for decoding a GSM signal in which the transmission of the audio data over the network is commenced prior to the completing of the decoding process (202).</p> |
