标题： Massive MIMO with 1-bit ADC

摘要： 我们研究使用1位模数转换器(ADC)的大量多输入多输出(MIMO)上行链路系统，每个接收天线都使用1位ADC。 依赖1位ADC的接收器不需要消耗能量的接口，如自动增益控制(AGC)。 这降低了ADC的构建和运行成本。 我们的设计基于最大比合并(MRC)、零 forcing(ZF)和最小二乘法(LS)检测，在考虑1位ADC对信道估计的影响时进行设计。 通过数值结果，我们展示了系统在互信息和符号错误率(SER)方面的良好性能。 此外，我们提供了一种分析方法来计算MRC接收器的互信息和SER。 这种分析方法在复杂度方面有所降低，因为避免了符号和信道噪声向量的蒙特卡洛仿真。 显示英文摘要

摘要： We investigate massive multiple-input-multiple output (MIMO) uplink systems with 1-bit analog-to-digital converters (ADCs) on each receiver antenna. Receivers that rely on 1-bit ADC do not need energy-consuming interfaces such as automatic gain control (AGC). This decreases both ADC building and operational costs. Our design is based on maximal ratio combining (MRC), zero-forcing (ZF), and least squares (LS) detection, taking into account the effects of the 1-bit ADC on channel estimation. Through numerical results, we show good performance of the system in terms of mutual information and symbol error rate (SER). Furthermore, we provide an analytical approach to calculate the mutual information and SER of the MRC receiver. The analytical approach reduces complexity in the sense that a symbol and channel noise vectors Monte Carlo simulation is avoided.
