发明名称 Interference carrier regeneration and interference cancellation apparatus and methods
摘要 Interference carrier regeneration and interference cancellation involve generating a Cross Polarization Interference Cancellation (XPIC) error signal representative of a difference between a first signal derived from a first communication signal that is received over a wireless communication link and a first symbol decision that is based on the first signal. The first communication signal is affected by interference from a second communication signal, on an orthogonal polarization channel of the same nominal frequency channel, for example. Based on the XPIC error signal and a second symbol decision for the second communication signal, a carrier of interference affecting the first signal from the second communication signal is regenerated. A rotation and derotation arrangement rotates a cross-channel interference signal and derotates a main channel equalizer feedback signal based on the regenerated interference carrier. The derotated main channel equalizer feedback signal can be provided as a feedback signal to a cross-channel interference equalizer.
