Abstract The impact of spatial correlation on performance of unitary space-time codes is focused on in this paper. Based on pair-wise error probability the upper bound of bit and codeword error ratio are given in this paper. The proof of equivalence between the derived result and existed result is presented when the channels are independent. Mento-Carlo simulation results show that the spatial correlation results in performance loss and the amount of this loss depends on the extent of spatial correlation.
