Massive multiple-input multiple-output (MIMO) systems have attracted much attention lately due to the many advantages they provide over single-antenna systems. Owing to the many antennas, low-cost implementation and low power consumption per antenna are desired. To that end, massive MIMO structures with low-resolution analog-to-digital converters (ADC) have been investigated in many studies. However, the effect of a strong interferer in the adjacent band on quantized massive MIMO systems have not been examined yet. In this study, we analyze the performance of uplink massive MIMO with low-resolution ADCs under frequency selective fading with orthogonal frequency division multiplexing (OFDM) in the perfect and imperfect receiver channel state information cases. We derive analytical expressions for the bit error rate and ergodic capacity. We show that the interfering band can be suppressed by increasing the number of antennas or the oversampling rate when a zero-forcing receiver is employed.

邻信道干扰下过采样量化上行链路大规模MIMO-OFDM的性能分析

由于与单天线系统相比，大规模多输入多输出 (MIMO) 系统具有许多优势，因此近来备受关注。由于有许多天线，需要低成本的实现和每根天线的低功耗。为此，许多研究已经研究了具有低分辨率模数转换器 (ADC) 的大规模 MIMO 结构。然而，尚未研究相邻频段中强干扰对量化大规模 MIMO 系统的影响。在这项研究中，我们分析了在具有正交频分复用 (OFDM) 的频率选择性衰落下，在完美和不完美的接收器信道状态信息情况下，使用低分辨率 ADC 的上行链路大规模 MIMO 的性能。我们推导出误码率和遍历容量的解析表达式。
