摘要：

Several new results are presented for optimum (diversity) combining with imperfect channel estimates (OC-ICE). A thresholding effect is demonstrated for the Rician fading channel; it is shown that the OC-ICE performance is near optimal (i.e., similar to that for the maximum ratio combiner (MRC)) below a (Rician K factor dependent) threshold irrespective of the pilot channel received SNR. Above the threshold, the performance degrades and in certain cases approaches the performance of the Rayleigh fading case. A new analytical evaluation of the bit error probability of the OC-ICE in Rician fading is presented. This analysis is based on an observation made in this paper that an effect of imperfect channel estimates is to effectively lower the Rician K factor.
