Multiuser performance analysis of MIMO-MRC systems under co-channel interference and channel estimation error

In this paper, considering the channel estimation error and the presence of co-channel interferences (CCIs), we analyze the performance of multiuser multiple-input multiple-output wireless systems employing transmit beamforming and maximum ratio combining (MIMO MRC). Exact closed-form cumulative distribution function expression of the signal-to-noise-plus-interference ratio (SINR) is derived. Second, we present the average capacity of MIMO MRC systems with multiuser diversity. Numerical results demonstrate the accuracy of our analytical expressions.
