ANALOG INTERFERENCE CANCELATION FOR SHARED ANTENNAS

摘要

Various aspects described herein relate to providing analog interference cancelation in a shared antenna. A plurality of signals can be obtained at a plurality of reference points in a transmitter chain of a shared antenna. At least one reference point of the plurality of reference points from which to generate a cancelation signal and/or at least one injection point for injecting the cancelation signal can be selected based at least in part on expected analog interference cancelation metrics related to each of the plurality of reference points and/or the at least one injection point. The cancelation signal can be generated based at least in part on the at least one reference point and/or injection point. The cancelation signal can be injected in the injection point at a receiver chain of the shared antenna to cancel interference from signals generated at the transmitter chain of the shared antenna.

1. A method for providing analog interference cancelation in a shared antenna, comprising:
obtaining a plurality of signals at a plurality of reference points in a transmitter chain of a shared antenna; selecting at least one reference point of the plurality of reference points from which to generate a cancelation signal and/or at least one injection point for injecting the cancelation signal based at least in part on expected analog interference cancelation metrics related to each of the plurality of reference points and/or the at least one injection point; generating the cancelation signal based at least in part on the at least one reference point and/or the at least one injection point; and injecting the cancelation signal in the at least one injection point at a receiver chain of the shared antenna to cancel interference from signals generated at the transmitter chain of the shared antenna.
