摘要

This review paper studies the performance of massive MIMO uplink system over Rician fading channel. The performance is measured in terms of spectral efficiency versus number of base station antennas using three schemes of linear detection, maximum-ratio-combining(MRC), zero forcing receiver(ZF), and minimum mean-square error receiver(MMSE). The simulation results show that the spectral efficiency increases significantly with increasing the number of base station antennas. Also, the spectral efficiency with MMSE is better than that with ZF, and the latter is better than that with MRC. In addition, the spectral efficiency decreases with increasing the fading parameter.

本文研究了大規模MIMO上行鏈路系統在Rician衰落信道上的性能。使用線性檢測，最大比率組合（MRC），迫零接收器（ZF）和最小均方誤差接收器（MMSE）三種方案，以頻譜效率與基地台天線數量來衡量性能。仿真結果表明，隨著基地台天線數量的增加，頻譜效率顯著提高。 此外，MMSE的頻譜效率優於ZF，後者優於MRC。此外，頻譜效率隨著衰落參數的增加而降低。
