TRANSCEIVER FOR SELECTING A SOURCE CODER, PROCESSES CARRIED OUT IN SUCH A TRANSCEIVER, DIGITAL TELECOMMUNICATION SYSTEM, AND DIGITAL SIGNAL TRANSMISSION PROCESS

摘要

This invention is a wireless signal transceiver for receiving an audio signal input and generating an output signal at a given output rate relates to the non-speech signal is distorted as acceptable (an acceptable distortion ratio) for source coding the input signal in order to obtain sufficient compression for the desired output speed at the same time is maintained (source coding) in the wireless signal transceiver to be subjected to It relates. An object of the present invention is to improve the trade-off of transmission quality and transmission speed of the voice signal by selecting the optimum coder from the available coders (coder). For this purpose, the transceiver will check means for comparing the set value measuring means for measuring the distortion of the output signal of the encoder and the estimated distortion (the estimated distortion) and induce the best coder for the measured distortion include (check means).
