Abstract
The use of dual polarized transmission provides a means of doubling the spectral efficiency in radio communications systems. Antenna imperfections and/or non ideal channel conditions introduce cross-polarization interference, degrading the performance. Additionally, the performance may be further degraded by the presence of a narrow-band interferer. We propose a scheme which uses an antenna array, depolarizers, and an adaptive filtering algorithm to cancel the directional co-channel interference and decorrelate the polarized information bearing channels. The proposed structure is analyzed analytically and simulation results are presented for 4-QAM or QPSK signals.
