分析了大规模多输入多输出(MIMO)系统中基站采用低分辨率模数转换器时的上行链路性能。设计了一种同时考虑加性高斯白噪声(AWGN)和量化噪声的高性能MMSE接收机，该接收机适用于均匀分辨率ADC和非均匀分辨率ADC。对于所提出的MMSE接收机，我们利用随机矩阵理论推导出系统上行链路频谱效率(SE)的渐近等价。数值结果表明，采用低分辨率ADC的massive MIMO系统，通过增加基站天线数目，仍能获得令人满意的上行链路SE，且上行链路SE的渐近等价是紧密的。

英文摘要：
The uplink performance of massive multiple-input-multiple-output (MIMO) systems where the base stations (BS) employ low-resolution analog-to-digital converters (ADCs) is analyzed. A high performance MMSE receiver that takes both additive white Gaussian noise (AWGN) and quantization noise into consideration is designed, which works well for both cases of uniform resolution ADCs and non-uniform resolution ADCs. With the proposed MMSE receiver, we then employ the random matrix theory to derive the asymptotic equivalent of the uplink spectral efficiency (SE) of the system. Numerical results show the tightness of the asymptotic equivalent of the uplink SE, and massive MIMO with low-resolution ADCs can still achieve the satisfying uplink SE by increasing the number of antennas at BS.
