Abstract
Cross-polar interference cancellation in a dual-polarization system is described. A terminal in a satellite communication system may receive a first communication signal in a first polarization and a second communication signal in a second polarization substantially orthogonal to the first polarization. The terminal may correlate in-phase or quadrature components of the first communication signal with in-phase or quadrature components of the second communication signal to generate one or more correlation measurements. Correction terms may be generated, using the correlation measurements, to remove at least some of the cross-polar interference.
