After an extensive literature overview of experimental data, we present a new and simple analytical framework to model dual-polarized Rayleigh and Ricean fading channels for arbitrary array sizes. ...
The model relies on a limited number of physical parameters, such as the channel spatial correlations, the channel co-polar and the cross-polar ratios and the antenna cross-polar discrimination. ...
That implies that uplink XPR levels clearly depend on the Tx polarization. In [20] , XPR values as low as 3 dB are measured in an office environment at 2.4 GHz. ...
