论文摘要
在这封信中，研究了两个相位变化设计的影响，即随机相位变化和相干相位转移，对智能反射表面（IRS）辅助非正交多重访问（NOMA）的性能。开发了分析结果，以表明这两种设计在可靠性和复杂性之间实现了不同的权衡。提供了模拟结果，以将IRS-NOMA与常规中继和IRS辅助正交多访问进行比较，并验证获得的分析结果的准确性。
In this letter, the impact of two phase shifting designs, namely random phase shifting and coherent phase shifting, on the performance of intelligent reflecting surface (IRS) assisted non-orthogonal multiple access (NOMA) is studied. Analytical results are developed to show that the two designs achieve different tradeoffs between reliability and complexity. Simulation results are provided to compare IRS-NOMA to conventional relaying and IRS assisted orthogonal multiple access, and also to verify the accuracy of the obtained analytical results.
