Methods and apparatus for mitigating known interference
First Claim
1. A method for mitigating known interference at a receiving device, the method comprising:
- receiving a signal from a transmission source that is affected by an interference source;
determining at least one of i) a first pilot signal associated with the transmission source, and ii) a second pilot signal associated with the interfering source, wherein the first pilot signal includes information broadcast from the transmission source and the second pilot signal includes information broadcast from the interference source; and
mitigating interference caused by the interference source from the received signal using at least one of i) the first pilot signal and ii) the second pilot signal, wherein mitigating the interference caused by the interference source comprises generating an interference whitened received signal based on an interference correlation matrix.

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.
