For the downlink of multi-user and multi-cell wireless Multiple-Input Multiple-Output (MIMO) communication system, there are three cases in the case of channel imperfection: the transmitter considers impairment but the receiver is ideal, the receiver consid-ers impairment but the transmitter is ideal and the transceiver considers impairment. We propose the corresponding system performance optimization algorithm through beamforming de-sign, and the differences of the system performance under three conditions are compared without considering impairment. The simulation results show that the robustness of three cases are better than that without considering the impairment at the trans-ceiver in the probabilistic constrained channel.
