Abstract

For optimal polarization reception in the presence of interference and noise, a new signal-to-interference-and-noise-ratio (SINR) equation is derived from two triangles in polarization sphere based on the polarization ellipse parameters. The local optimal solutions of SINR on the great circle tracks and the small circle tracks are obtained. Some analytic solutions in special polarization schemes are presented. Several optimal strategies are proposed. An optimal polarization scheme called Three Steps' Searching and Comparing (TSSC) is suggested. The comparison among these optimal schemes is given. Simulation results show that TSSC scheme closely approaches the global optimum quickly and efficiently.
