Optimal power allocation (PA) strategies can make a significant rateimprovement in secure spatial modulation (SM). Due to the lack of secrecy rate(SR) closed-form expression in secure SM networks, it is hard to optimize thePA factor. In this paper, two PA strategies are proposed: gradient descent, andmaximum product of signal-to-interference-plus-noise ratio (SINR) andartificial-noise-to-signal-plus-noise ratio (ANSNR)(Max-P-SINR-ANSNR). Theformer is an iterative method and the latter is a closed-form solution.Compared to the former, the latter is of low-complexity. Simulation resultsshow that the proposed two PA methods can approximately achieve the same SRperformance as exhaustive search method and perform far better than three fixedPA ones. With extremely low complexity, the SR performance of the proposedMax-P-SINR-ANSNR performs slightly better and worse than that of the proposedGD in the low to medium, and high signal-to-noise ratio regions, respectively.
