On the Asymptotic Performance of Receive Space Modulation in the Shadowing Broadcast Channel

In this paper, the diversity order and coding gain of Receive Space Modulation (RSM) in the Multiple-InputMultiple- Output (MIMO) broadcast channel are derived by taking into account both small and large scale fading. The considered linear precoding method is Zero Forcing (ZF). Note that the proposed framework is directly applicable to the conventional spatially multiplexed broadcast channel. Based on the derived mathematical framework, a theoretical criterion is provided which determines the superiority between the deployment of RSM and Spatial MultipleXing (SMX) in the shadowing MIMO broadcast channel. Finally, the provided theoretical results are validated via Monte Carlo simulation results.
