摘要:

在本文中,我们推导出智能反射面(IRS)辅助毫米波(mmWave)系统的上行链路可达速率的表达式,考虑到相位噪声在IRS和量化误差在基站(BS)。我们表明,性能是有限的,只有在BS的模拟数字转换器(ADC)的分辨率时,IRS反射器的数量增长没有约束。另一方面,如果BS具有理想的ADC,则由IRS相位噪声引起的性能损失是恒定的。最后,我们的研究结果验证了在IRS中使用低精度硬件的可行性,当BS配备低分辨率ADC时。

英文摘要:

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.
