Amplitude Phase Shift Keying Aided Rectangular Differential Spatial Modulation

本文提出了一种用于多输入多输出(MIMO)系统的结合幅度相移键控(ASPK)的新型差分空间调制方法。该方法结合APSK与RDSM调制,在保留了RDSM矩形天线索引矩阵的结构下,利用APSK调制来进一步提升了频谱效率。通过仿真结果比较了所提算法相比于传统差分空间调制的性能差异。

In this paper, a novel amplitude phase shift keying Aided rectangular differential spatial modulation(APSK-RDSM) is proposed for multiple-input and multiple-out(MIMO) system, which combines the amplitude phase shift keying(APSK) and rectangular differential spatial modulation(RDSM) to take the advantages of RDSM and STBC systems, while avoiding the drawbacks of conventional differential spatial modulation(DSM) systems. Finally, simulation results demonstrate that APSK-RDSM outperforms the conventional DSM systems for various spectral efficiencies.
