摘要：The huge increase of the MIMO (multiple input multiple output) capacity required perfect channel knowledge at the receiver. In this paper, we analyze the effect of imperfect channel estimation error on MIMO systems’ BER performance. By utilizing whitening-rotation (WR) algorithm for recovering the detected signal at the receiver and calculating channel coefficients, it can be proved that semi-blind channel estimation obtains better results in comparison with blind ones. In addition, we also analyze symbol error rate (SER) of MIMO systems in such estimation schemes.
