摘要
作为5G关键技术之一,Massive MIMO技术通过提供更灵活的空间复用能力可以有效提高系统容量和频谱利用率。但Massive MIMO信道更加复杂的传播特性使Massive MIMO信道模型的研究成为难点,大多数算法存在复杂度过高的问题,系统性建模仿真非常缺乏。对大规模MIMO无线信道建模的研究现状进行了介绍和分析,提出了一种适用于实际网络规划的Massive MIMO信道建模方法,并进行系统级仿真验证。
As one of the 5 G key technologies,Massive MIMO technology can effectively improve system capacity and spectrum utilization by providing more flexible spatial multiplexing capability. However,the more complex propagation properties of the Missive MIMO channel make the research and development of the Missive MIMO channel model difficult,and system simulation on channel modeling is also very lacking. It introduces and analyzes the existed studies of Massive MIMO wireless channel models. A Massive MIMO channel modeling method suitable for realistic network planning is proposed and system level simulation is performed.
