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.

本文研究了智能反射面辅助毫米波系统的上行可达速率表达式，考虑了智能反射面的相位噪声和基站（BS）的量化误差，结果表明当智能反射面的反射器数量趋近无限时，性能仅受到 BS 模数转换器分辨率的限制；另一方面，如果 BS 具有理想的 ADC，则智能反射面相位噪声导致的性能损失是恒定的；最后，研究结果验证当 BS 装备低分辨率 ADC 时，智能反射面可以使用低精度硬件实现。
