摘要

本文提出了一种可重构智能表面(RIS)辅助空间调制的差分方案，即RIS- dsm，以消除接收机对信道状态信息(CSI)的需求。该方案是对当前基于ris系统的差分调制方案的改进，因为它避免了高阶矩阵计算并提高了频谱效率。建立了一个数学框架，利用RIS-DSM确定系统的理论平均误码率(ABEP)。通过简化，所提出的RIS-DSM方案的检测复杂度极低。最后，仿真结果表明，即使在低信噪比环境下，RIS-DSM方案也能提供令人满意的误差性能。

Differential scheme for reconfigurable intelligent surface-based spatial modulation system

In this paper, a differential scheme is proposed for reconfigurable intelligent surface (RIS) assisted spatial modulation, which is referred to as RIS-DSM, to eliminate the need for channel state information (CSI) at the receiver. The proposed scheme is an improvement over the current differential modulation scheme used in RIS-based systems, as it avoids the high-order matrix calculation and improves the spectral efficiency. A mathematical framework is developed to determine the theoretical average bit error probability (ABEP) of the system using RIS-DSM. The detection complexity of the proposed RIS-DSM scheme is extremely low through the simplification. Finally, simulations results demonstrate that the proposed RIS-DSM scheme can deliver satisfactory error performance even in low signal-to-noise ratio environments.
