| Abstract: | It discusses the influence of antenna directivity on cross polarization discrimination (XPD) in digital microwave communications, the relation between equivalent Rayleigh fading probability and XPD exacerbated quantity. Finally, it explains that the exacerbation influence of multipath fading on XPD can be decreased by taking some technical measures. |
