The impact of channel correlation on the performance of polarization divercity combining

In fact, there is relativity between the two branches of the polarization diversity-receiving antenna, so, this paper analyzes the effect of the channel correlation to the performance of polarization diversity combining, and gives the method of the generation of the correlated channels. The emulation was used to study the performance. In maximal ratio combining of Rayleigh channel, when each branch´s average SNR is relatively small compared to the threshold, our results show that the probability that the output SNR exceeds the given threshold grows as the correlation coefficient increases.
