This paper addresses the performance degradation of multiple-input multiple-output (MIMO) communication systems due to MIMO wireless transceiver radio frequency integrated circuits (RFIC) imperfections. The effects of signal coupling in RF front-end, frequency synthesizer phase noise, and the gain imbalance between different radio paths are investigated. These issues are explored by analytical derivations and results are verified by Monte Carlo simulations. The analytical model achieves a good agreement with the simulation results. The conclusion can serve as a useful reference for MIMO RFIC designers.
