During the last few years, evaluation of MIMO systems capacity has been expanded, due to more bandwidth demands. In this paper, after reviewing the previous works, a new formula for MIMO systems capacity, in the case of uniformly distributed channel error is given. While in previous works, Gaussian distribution is the preliminary assumption of almost all, we have switched to uniform case, because the channel error comes from the quantization techniques used in receiver to send the information of channel through a partial feedback path to the transmitter and these techniques in nature make uniform distribution error.
