摘要

本文研究了基站(BS)天线配置为均匀圆形平面阵列(UCPA)的大规模多输入多输出(MIMO)系统的和速率。所考虑的信道是由每个用户的天线转向矢量控制的视距(LOS)。假设用户方位角和仰角独立且均匀分布。由于其低复杂性和低至中等信噪比(SNR)的可接受性能，BS执行最大比传输(MRT)波束形成。然后分析和速率性能，并与大规模MIMO中假设有利传播获得的和速率上界进行比较。结果表明，天线数量的增加增加了和速率曲线的斜率。

Sum Rate of Massive MIMO Systems Deploying Uniform Circular Planar Array Base Station Antenna

We consider the sum rate of massive multiple input multiple output (MIMO) systems where the base station (BS) antenna configuration is uniform circular planar array (UCPA). The channel considered is line-of-sight (LOS) governed by the antenna steering vector of each user. The user azimuth and elevation angles are assumed independent and uniformly distributed. The BS performs maximum ratio transmission (MRT) beamforming due to its low complexity and acceptable performance for low to moderate signal-to-noise ratio (SNR). The sum rate performance is then analyzed and compared to the upper bound sum rate obtained by assuming favorable propagation in massive MIMO. It is shown that using a larger amount of antennas increases the slope of the sum rate curve.
