Abstract—Generalized space shift keying (GSSK) has recently attracted much interest in the study of emerging massive MIMO systems. The maximum likelihood (ML) detection of GSSK can be posed as a 0-1 quadratic program with an equality constraint. The

广义空移键控(GSSK)的特点是在每一时隙只激活部分发射天线，利用激活天线的索引号来传递信息。基于最大似然(ML)准则的GSSK检测器有最优的检测性能，但计算复杂度太高。为了在性能和复杂度之间取得更好的折中，改进了一种基于压缩感知(CS)的GSSK检测算法。仿真结果表明，该算法的检测性能接近于ML算法，且复杂度约为ML算法的2%。
