Detection with spatial diversity using noisy channel estimates in a correlated fading channel
P. Shamain, L.B. Milstein · 2003
Usually, diversity reception, either with or without perfect channel state information (CSI), is studied with independent fades. In this paper, the condition for independence is relaxed, and the effect of fade correlation on both the diversity gain and the accuracy of channel estimation for a direct sequence spread spectrum (DSSS) system employing pilot-aided, coherent, spatial-diversity reception under the most general form of correlated Rayleigh fading is assessed.
