Error Performance of Magic Square Based Generalized SM for UAV Communication

Abstract

In this study, we propose a new method for generalized spatial modulation, which provides more reliability, lower power consumption, and better bit error rate performance for unmanned aerial vehicle (UAV) communication. This new method is based on active antenna utilization with the possible combinations that help diverge between symbols from the constellation diagram. Provision of this divergence between antennas is based on magic square phenomena that are new for communication systems usage. Thanks to the ergonomic architecture of the antenna selection method, the method can be used for different transmit antennas and different conventional modulation orders. It is shown that the new method outperforms conventional generalized spatial modulation (GSM) for air-to-air (A2A) and air-to-ground (A2G) UAV communication with the basis of aforementioned metrics.
