Performance Analysis of MIMO MRC Systems in the Presence of Self-Interference and Co-Channel Interferences

Both self-interference (SI), which is caused by imperfect channel estimation, and co-channel interference (CCI) are considered in multiple-input multiple-output systems employing maximal ratio combining under independent and identically distributed Rayleigh fading. Closed-form expressions for probability density function and outage probability of output signal-to-interference plus noise ratio are presented. Numerical results are used to evaluate the impact of SI and CCI.
