Canceling far end cross-talk in communication systems

摘要

A method and system are described for canceling far end cross-talk in communication systems. A first transmitter transmits the first effective data source signals across the first channel. A second transmitter transmits the second effective data source signals across the second channel. In one embodiment, a receiver unit receives first and second effective data source signals across a first channel and a second channel, respectively, and also one or more cross-talk signals. A far end cross talk (FEXT) canceller located in the receiver unit receives second estimated effective data source signals based on the second effective data source signals. The receiver unit cancels the one or more cross-talk signals using the second estimated effective data source signals.
