In this paper, we present the re-configurable intelligent surfaces (RIS) based space shift keying (SSK) and spatial modulation (SM) schemes with both perfect and imperfect channel phase knowledge over Weibull fading environments. At the receiver, we consider the sub-optimal Greedy Detection (GD) for proposed RIS-based SSK and SM schemes. Central Limit Theorem (CLT) caused by RIS schemes facilitates to adopt of a unified framework for error performance analysis of Weibull fading channels without loss of generality. In this study, it has been obtained the theoretical bit error probability (BEP) of the proposed schemes. It should be underlined that unlike the literature, the BEP of the proposed schemes is formulated in the presence of a Gaussian imperfect phase estimation at RIS. These analytical results were then validated with Monte-Carlo Simulations under the various system settings (e.g., the severity of fading parameters, number of reflectors, different antenna numbers).

在本文中，我们提出了基于可重构智能表面（RIS）的空间移位键控（SSK）和空间调制（SM）方案，并在Weibull衰落环境中具有完美和不完美的信道相位知识。在接收机处，我们考虑针对基于RIS的SSK和SM方案的次优贪婪检测（GD）。RIS方案引起的中心极限定理（CLT）有助于采用统一的框架来进行威布尔衰落信道的误码性能分析，而不会失去一般性。在这项研究中，已经获得了所提出方案的理论误码率（BEP）。应该强调的是，与文献不同，提出的方案的BEP是在RIS处存在高斯不完美相位估计的情况下制定的。
