Apparatus and method of echo-cancellation |
摘要 |
There is disclosed a multi-carrier transceiver system for use in echo-cancellation. The transceiver system is arranged to generate from input data (1) a multi-carrier transmit signal (u) 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 (Yi) received from a remote signal transmitter. An echo canceller (2000) is arranged to generate from a pair of multi-carrier data blocks (u) a set of frequency-domain echo parameters (W) for use in generating an echo signal (Y< LAMBDA >), to generate the echo signal using the frequency-domain echo parameters (W), and to input the echo signal (Y< LAMBDA >) to the multi-carrier signal receiver for use in generating an echo-cancelled receive signal (Ei) from the input receive signal (Yi) and the echo signal (Y< LAMBDA >). <IMAGE> |
