Abstract :
In this letter, we analyze the performance of multiple-input multiple-output (MIMO) wireless communications with transmit beamforming and maximum ratio combining (MRC), known as MIMO-MRC, with channel estimation error in the presence of cochannel interferences (CCIs). The quantified measure for channel estimation error is the correlation coefficient between the true fading channel coefficients and their estimates. Exact closed-form expressions for the statistical distribution of the signal-to-noise-plus-interference ratio (SINR), the outage probability of the SINR, and the average symbol error rate (ASER) for some modulation formats are derived. The analytical results are confirmed by numerical simulations.
