Frequency-Domain Analysis of a Cross Polarization Interference Canceller under Multipath Fading for Digital Radio Systems
Summary :
This paper describes the frequency-domain analysis of a cross polarization interference canceller (XPIC) combined with a waveform equalizer. Analytical formula of the XPIC constructed by a multi-tap transversal filter is described under two-ray fading model. The XPIC performance relative to the correlation between the vertical and horizontal polarizations is also investigated by calculating the post-XPIC residual interference as a parameter of tap numbers. The improvement of disired-to-undesired signal ratio by the XPIC is discussed among three typical fading patterns. When co-polarization is dispersive with the same notch frequency (high correlation) and the cross polarization interference is non-dispersive, the XPIC performance is most degraded. The XPIC performance is better for fading events of non-dispersive co-polarization and dispersive cross polarization interference. Moreover, this paper shows the difference of the XPIC performance between the two types of receiver which obtain the reference signal from either post-equalizer or pre-equalizer.
