Polarization filtering has attracted a great interests for it can be used to solve problems of signal separation and interference suppression those are difficult to process in the time, frequency and spatial domains. Polarization information of both target signal and interference are needed to design the polarization filter in the conventional method, while exact estimation of the polarization information...
Based on the oblique projection operators, a novel method for interference suppressing named oblique projection polarization filter (OPPF) in the polarization domain is proposed, which is valid for nonorthogonal polarization filtering or projecting. After discussing the fundamental principle of the proposed OPPF in detail, simulation results are given to illustrate the suggested scheme is suitable...
