Analog interference cancellation for shared antenna

摘要

Various aspects described herein relate to providing analog interference cancellation in a shared antenna. Multiple signals may be acquired at multiple reference points in the transmitter chain of the shared antenna. At least one reference point of a plurality of reference points for generating a cancel signal and / or at least one injection point for injecting a cancellation signal may be generated for each of a plurality of reference points and / or at least one injection point Based on at least in part on the expected analog interference cancellation metric associated with the received signal. The cancellation signal may be generated based at least in part on at least one reference point and / or injection point. The cancellation signal is injected into the injection point in the receiver antenna chain of the shared antenna in order to cancel the interference from the signal generated in the transmitter chain of the shared antenna.
