The ratio of co-pol power to the cross-pol converted “leakage” power is defined as cross-pol discrimination (XPD). The analysis presented in this article derives bit

What is Cross Polar Discrimination (XPD)? Definition of Cross Polar Discrimination (XPD): The ratio of the signals (desired) on the desired polarization to the signals (undesired) signals on the opposite polarization.

Axial ratio and cross polar discrimination (XPD) interference For circular polarisation the purity of the polarisation is specified in terms of axial ratio. To obtain the cross polar discrimination (XPD) interference refer to the following formula: XPD = 20 log ((r+1)/ (r-1)) dB. Cross-polarization discrimination (XPD) has a significant impact on the spatial correlation of the MIMO channel [26, 33] and according to the geometrical theory of channel depolarization [24] and The cross-polarization discrimination (XPD) of horizontal/vertical polarizations has been studied in different types of areas to show the influence of environment on the performance of a polarization diversity scheme. Enhanced Cross-Polarization Discrimination of Wideband Differentially Fed Dual-Polarized Antenna via a Shorting Loop Abstract: In this letter, a wideband differentially fed ±45° dual-polarized antenna with high cross-polarization discrimination (XPD) is proposed for base station applications. Axial ratio and cross polar discrimination (XPD) interference. For circular polarisation the purity of the polarisation is specified in terms of axial ratio. To obtain the cross polar discrimination (XPD) interference refer to the following formula: XPD = 20 log ( (r+1)/ (r-1)) dB.
