ECHO COMPENSATION METHOD, ECHO COMPENSATION DEVICE AND TELECOMMUNICATION DEVICE

摘要

The invention relates to an echo compensation method for a telecommunication device, comprising the following steps: production of at least one compensation signal (CM1, CM2) according to an output signal (OUT) of said telecommunication device by reproduction of the transmission characteristics of a transmission link, whereby non-linear distortions are taken into account, and compensation of echo components in an input signal (IN) of the telecommunication device according to the at least one compensation signal (CM1, CM2) in order to obtain an echo-compensated signal (RES). The method is further characterised in that non-linear distortions of the transmission link are taken into account by means of an adaptive method and that said adaptation is based on the echo-compensated signal (RES). An echo compensation device and a telecommunication device are provided to implement this method. The invention provides effective and flexible echo compensation even when there is strong non-linear distortion and requires only a small number (if any) of adjustments.
