Abstract

We study the effect of fading on estimating the antenna array response, and subsequently separating and estimating the unknown data streams. The results are presented in the form of output signal to interference ratio (SIR) and output signal to noise ratio (SNR). We obtain closed form expressions for the average output SNR and SIR for Rayleigh, Rician and Nagakami fading. It is shown that in the presence of slowly fading channels, the diversity advantage of the array decreases as the number of signals increases.
