Abstract
Rejecting radio frequency (RF) interference in a communication system. In one aspect, rejecting RF interference includes receiving a signal on a signal path of a receiver from a communication channel, the signal including one or more received signal components having a frequency within a predetermined subset range of frequencies within an operating signal bandwidth of the receiver. The received signal components are attenuated using a notch filter to reduce RF interference obtained during transmission of the signal over the communication channel. In some embodiments, the one or more signal components have been boosted in power at a link partner transmitter connected to the communication channel.
