本文提出了一种多输入多输出（MIMO）系统的空时分组编码矩形差分空间调制（STBC-RDSM）方案，该方案将空时分组编码（STBC）和矩形差分空间调制（RDSM）相结合，在避免传统差分空间调制（DSM）系统缺点的同时，获得各自的优点。更具体地说，在提出的STBC- rdsm方案中，信息位通过矩形差分编码天线索引矩阵和STBC块传输。此外，提出了一种低复杂度的检测方案。我们的仿真结果表明，STBC-RDSM在各种频谱效率方面都优于传统的DSM。最后，导出了误码率的封闭联合界，并通过仿真结果进行了验证。
In this paper, a novel scheme dubbed space-time block coded rectangular differential spatial modulation (STBC-RDSM) is proposed for multiple-input and multiple-out (MIMO) systems, which combines space-time block coding (STBC) and rectangular differential spatial modulation (RDSM) to reap their respective benefits while avoiding the drawbacks of conventional differential spatial modulation (DSM) systems. More specifically, in the proposed STBC-RDSM scheme, information bits are conveyed via the rectangular differentially encoded antenna index matrices, as well as the STBC blocks. Furthermore, a low-complexity detection scheme is proposed. Our simulation results demonstrate that STBC-RDSM outperforms its conventional DSM counterparts in various spectral efficiencies. Finally, a closed-form union bound on the bit error rate (BER) is derived and validated by our simulation results.
