摘要

同时发射和反射可重构智能表面(STAR-RISs)提供发射和反射信号。STAR-RIS和非正交多址(NOMA)的结合提供了更高的性能增益。在本文中，我们评估了星- ris在相位误差和收发器硬件损坏情况下的NOMA下行传输。我们利用有效信道功率的统计特性，评估了理想和非理想STAR-RIS-NOMA系统的遍历速率行为。数值结果证实了解析分析的准确性，并对系统参数的选择进行了论证。

Simultaneously Transmitting and Reflecting-Reconfigurable Intelligent Surfaces with Hardware Impairment and Phase Error

Simultaneously transmitting and reflecting reconfig-urable intelligent surfaces (STAR-RISs) provide both transmitting and reflecting signals. The combination of STAR-RIS and non-orthogonal multiple access (NOMA) provides higher performance gains. In this paper, we evaluate NOMA downlink transmission with STAR-RIS under phase error and transceiver hardware impairment. We exploit the statistical properties of the effective channel power and evaluate the ergodic rate behaviors for ideal and non-ideal STAR-RIS-NOMA systems. The numerical results confirm the accuracy of the analytical analysis and demonstrate the selection of the system parameters.
