Abstract
There is disclosed a multi-carrier transceiver system for use in echo cancellation. The transceiver system is arranged to generate from input data a multicarrier transmit signal comprising a plurality of multi-carrier data blocks. The transceiver system also has a multi-carrier signal receiver responsive to an input multi-carrier receive signal received from a remote signal transmitter. An echo canceller is arranged to generate from a pair of multi-carrier data blocks (u) a set of frequency-domain echo parameters for use in generating an echo signal, to generate the echo signal using the frequency-domain echo parameters, and to input the echo signal to the multi-carrier signal receiver for use in generating an echo-cancelled receive signal from the input receive signal and the echo signal.
