摘要

Against the poor average bit error probability (ABEP) and capacity performance of Generalized Spatial Modulation (GSM) system in correlated fading channels, we propose a technique called the Distance and Norm based Antenna Selection (DN-AS). In this method, we improve the capacity of both the spatial and signal constellations of GSM as much as possible. By jointly considering the distance metric of the channel column space and the channel gain norm, antennas are discarded from the candidate antenna set according to the greedy algorithm until a suboptimal antenna set is obtained. Simulations demonstrate substantial ABEP and capacity performance improvement of our scheme over the existing baseline algorithms at all signal-to-noise ratio (SNR) without significant increase in computational complexity. In addition, the proposed scheme can be readily applied to independent fading channels and maintain the same or even better performance.
