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.

具有低分辨率 ADC 和相位噪声的智能反射表面辅助毫米波通信的上行链路可实现速率

在本文中，我们推导了智能反射面 (IRS) 辅助毫米波 (mmWave) 系统的上行链路可实现速率表达式，同时考虑了 IRS 的相位噪声和基站 (BS) 的量化误差。我们表明，当 IRS 反射器的数量无限制地增长时，性能仅受 BS 处的模数转换器 (ADC) 分辨率的限制。另一方面，如果基站具有理想的 ADC，则由 IRS 相位噪声引起的性能损失是一个常数。最后，我们的结果验证了当 BS 配备低分辨率 ADC 时在 IRS 使用低精度硬件的可行性。
