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.
