Joint intersymbol interference and cross-pol interference cancellation for dually-polarized radio systems

The issues of joint intersymbol interference and cross-polarized channel-interference-cancellation for dually-polarized digital microwave radio systems are addressed. Several two-stage cancelers and one three-stage canceler are presented, and compared to more conventional receivers based on a generalization of adaptive equalization to dually-polarized radio systems. The results show that although the ideal canceler considerably outperforms the ideal decision-feedback receiver, practical cancelers lose most of this advantage.<>
