The innovative idea of data transmission through a reconfigurable intelligent surface (RIS) is a promising and exciting solution to the ever-present problems in wireless communications, such as energy consumption and hardware cost. The soft-controlled dynamic shaping of the electro-magnetic waves, which enables utilizing the randomness of the propagation medium to achieve more efficacious wireless channels, makes RIS a key enabler of 6G technology. Lately, space modulation techniques (SMTs) have often been discussed within the realm of the RIS-aided technologies due to their unique transmission characteristics. However, RIS-SMTs require more generalized and in-depth investigations to fully understand their potential in future generations. Accordingly, in this study, a recently proposed RIS-based SMT is generalized to inherently increase the spectral efficiency by utilizing spatial modulation (SM) procedure instead of space shift keying (SSK). The novel system called power-sensing RIS-SM is analyzed in the presence of improper Gaussian noise (IGN) to discover system behavior in the case of being corrupted by an improper interfering signal over Nakagami- channels, which adapt closely to the most of measured fading channels. The success of the proposed RIS-aided SMT is assessed in terms of the average bit error rate (ABER), which is both calculated by analytical derivations and verified by computer simulations.

关于功率传感 RIS-SM 的性能：不当高斯噪声和 Nakagami-m 衰落信道的影响

通过可重构智能表面（RIS）进行数据传输的创新理念是解决无线通信中始终存在的问题（例如能耗和硬件成本）的一种有前途且令人兴奋的解决方案。电磁波的软控制动态整形能够利用传播介质的随机性来实现更有效的无线信道，这使得 RIS 成为 6G 技术的关键推动者。最近，空间调制技术 (SMT) 由于其独特的传输特性而经常在 RIS 辅助技术领域内进行讨论。然而，RIS-SMT 需要更广泛和深入的研究，以充分了解其在后代中的潜力。因此，在本研究中，最近提出的基于 RIS 的 SMT 被推广到通过利用空间调制 (SM) 过程而不是空移键控 (SSK) 来固有地提高频谱效率。被称为功率传感 RIS-SM 的新型系统在存在不正确的高斯噪声 (IGN) 的情况下进行分析，以发现在 Nakagami 通道​​上被不正确的干扰信号破坏的情况下的系统行为，该系统紧密适应大多数测量的衰落通道。所提出的 RIS 辅助 SMT 的成功根据平均误码率 (ABER) 进行评估，该值既通过分析推导计算，又通过计算机模拟验证。
