论文摘要
由于它们在单一安德滕纳系统中提供的许多优势,最近大量的多输入多输出(MIMO)系统最近引起了很多关注。由于许多天线,需要低成本实施和每个天线的低功耗。为此,在许多研究中研究了具有低分辨率类似物转换器(ADC)的大规模MIMO结构(ADC)。但是,尚未检查相邻频带中强干扰物对量化大规模MIMO系统的影响。在这项研究中,我们分析了上行链路大量MIMO的性能,低分辨率ADC在频率选择性褪色下,正交频施加在完美和不完美的接收器通道状态信息案例中多路复用。我们得出了分析表达式的位误差率和偏僻的能力。我们表明,当使用零效率接收器时,可以通过增加天线数量或过采样率来抑制干扰带。
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 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.
