ABSTRACT:
A new receiver structure is disclosed for a full-duplex modem in which a fractionally spaced equalizer, which is normally present to mitigate the effects of linear impairments present on a communication channel, also performs echo cancellation. Specifically, an additional echo signal is formed in the full-duplex modem and added to a received signal, which includes an echo signal, thereby forming a composite signal. This composite signal is then applied to the fractionally spaced equalizer for equalization, which mitigates the echo signal.
