Optimal Power Allocation in Spatial Modulation Systems
IEEE Transactions on Wireless Communications, 2017 In spatial modulation (SM) systems, when channel state information is available at the transmitter, adaptive power allocation can be exploited to enhance the SM performance. In this paper, optimal power allocation in SM systems is considered from an information-theoretical view.
