1. A method comprising:
receiving a downlink reference signal from a downlink path;
generating, by a non-duplexer isolator sub-system, a mitigation signal from the downlink reference signal by mitigating uplink frequency components in the downlink reference signal; and
mitigating, by the non-duplexer isolator sub-system, downlink frequency components in an uplink signal traversing an uplink path by combining the mitigation signal with the uplink signal.
