论文摘要
这封信调查了非正交多访问（NOMA）网络中同时传输和反映可重构智能表面（Star-riss）的位错误率（BER）性能。在调查的网络中，星际统治通过使用模式切换协议来为位于表面两侧的多个非正交用户提供服务。我们以完美和不完美的连续干扰取消案例来得出封闭形式的表达式。此外，还进行了渐近分析，以提供对高信噪比区域中BER行为的进一步见解。最后，通过蒙特卡洛模拟验证了我们的理论分析的准确性。获得的结果表明，Star-Ris-Noma的BER性能优于经典Noma系统的BER性能，而Star-Ris可能是有希望的Noma 2.0解决方案。
This letter investigates the bit error rate (BER) performance of simultaneous transmitting and reflecting reconfigurable intelligent surfaces (STAR-RISs) in non-orthogonal multiple access (NOMA) networks. In the investigated network, a STAR-RIS serves multiple non-orthogonal users located on either side of the surface by utilizing the mode switching protocol. We derive the closed-form BER expressions in perfect and imperfect successive interference cancellation cases. Furthermore, asymptotic analyses are also conducted to provide further insights into the BER behavior in the high signal-to-noise ratio region. Finally, the accuracy of our theoretical analysis is validated through Monte Carlo simulations. The obtained results reveal that the BER performance of STAR-RIS-NOMA outperforms that of the classical NOMA system, and STAR-RIS might be a promising NOMA 2.0 solution.
