Setup Optimization in Spatial Modulation Systems: A Simulation Study

This paper investigates setup optimization of Spatial Modulation (SM) systems. Specifically, the optimal pair of the number of the transmit antennas and the modulation order, for a given spectral efficiency, that minimizes the error rate at the receiver has been discussed. Interesting results regarding the behavior of bit error rate and symbol error rate versus different transmitter setups under different signal-to-noise regimes have been shown. Moreover, closed-loop and open-loop scenarios have been considered. The obtained results contrast with the results available at literature, and lead to interesting conclusions about the optimal setup for SM systems.
