Impact of Co-Channel MIMO Interference on Desired Downlink Receiver Using STBC

The impact of three typical interfering MIMO modes, namely,Space-time block coding (STBC), open-loop spatial multiplexing andclosed-loop spatial multiplexing, on a desired downlink receiverusing STBC is investigated. The closed-form probability densityfunctions of signal-to-interference-plus-noise ratio are derived andused to analyze the performance of the desired receiver. Simulationresults verify the validity of the analytical results. Boththeoretical analyses and simulation results show that these threeco-channel MIMO interfering modes have almost the same impact on thedesired downlink STBC receiver.
