Method and arrangement for compensating signal echoes during duplex data transmission with discrete multitone modulation

摘要

Method and a device for compensating signal echoes during duplex data transmission with discrete multitone modulation In the method, during an initialization phase of a data transmission with discrete multitone modulation in the frequency domain a first error of a first reference channel is determined from the difference between the transmission value and the reception value of a signal of this channel and is used to correct the remaining frequency channels. The correction of the first reference channel is carried out by means of the error of a second reference channel.
