Interference Mitigation

About

The invention is a method for mitigating interference for a received wireless signal. The method comprises receiving a wireless signal with a receiver device, wherein the wireless signal contains both an interference signal and a desired signal; breaking the received wireless signal into sub-bands; and filtering the received wireless signal with a polarization filter, in order to separate the interference signal from the desired signal. The method can further comprise processing the wireless signal for retrieving the desired signal, or more specifically, the transmitted information/data. The wireless signal can operate in various domains, including for example but not limited to an orthogonal frequency division multiplexing (OFDM) system, a code division multiple access (CDMA) system, and the like. According to one aspect of the invention, the polarization filter used to filter the received wireless signal is a frequency-based polarization filter.
