论文摘要
在本文中，考虑到IRS处的相位噪声以及基础站点（BSS）的量化误差，我们得出了智能反射表面（IRS）辅助表面（IRS）辅助表面（IRS）的上行速率表达。我们表明，仅当IRS反射器的数量增长而没有结合时，仅受BSS的模拟数字转换器（ADC）的分辨率而限制性能。另一方面，如果BS具有理想的ADC，则IRS相位噪声引起的性能损失是恒定的。最后，我们的结果验证了当BSS配备低分辨率ADC时，在IRS上使用低精确硬件的可行性。
In this paper, we derive the uplink achievable rate expression of intelligent reflecting surface (IRS)-aided millimeter-wave (mmWave) systems, taking into account the phase noise at IRS and the quantization error at base stations (BSs). We show that the performance is limited only by the resolution of analog-digital converters (ADCs) at BSs when the number of IRS reflectors grows without bound. On the other hand, if BSs have ideal ADCs, the performance loss caused by IRS phase noise is a constant. Finally, our results validate the feasibility of using low-precision hardware at the IRS when BSs are equipped with low-resolution ADCs.
