ABSTRACT:
A system and method for compensating for signal echoes during duplex data transmission with discrete multitone modulation includes determining, the error of a first reference channel. The error of the first reference channel is determined in the frequency domain and is used to correct the other channels. The first reference channel is then corrected with a second error from a second reference channel.
