Methods and apparatus for mitigating known interference
First Claim
1. A method for mitigating interference in a receiving device, the method comprising:
- receiving a signal from a transmission source that is affected by interference from an interference source;
determining a first channel estimate corresponding to the transmission source;
determining, based on the first channel estimate, an expected improvement to be achieved in signal quality resulting from performing an interference mitigation operation; and
mitigating the interference caused by the interference source if the expected improvement to be achieved in signal quality exceeds a threshold, by finding a transmitted signal candidate that maximizes an average power of interference calculated based on the received signal and the first channel estimate, without using a second channel estimate corresponding to the interference source.

Abstract
Systems and methods for mitigating known interference at a receiving device are provided. A signal from a transmission source is received by a receiving device that is affected by an interference source. At least one of a first pilot signal associated with the transmission source and a second pilot signal associated with the interfering source is determined. The first pilot signal includes information broadcast from the transmission source and the second pilot signal includes information broadcast from the interference source. Interference caused by the interference source is mitigated from the received signal using at least one of the first pilot signal and the second pilot signal.
