不同于3G/4G信道,5G由于采用了大规模天线技术,使得5G Massive MIMO信道具有3D空间特性,因此需要研究5G Massive MIMO无线信道的验证方法,5G Massive MIMO无线信道的验证是5G基站多天线性能测试的关键。针对5G Massive IMMO信道的验证及测试,首先对5G Massive MIMO无线信道的生成及测试系统进行了介绍;然后利用PN相关序列,将PDP作为评价指标,研究了5G Massive MIMO信道多径个数、功率和时延的验证方法;随后基于矢量网络分析仪,提出了一种5G Massive MIMO信道多径角度的验证方法;最终形成了一套面向5G Massive MIMO性能评估的无线信道验证和测试方法。该方法实现了验证5G Massive MIMO信道准确性的目的,弥补了5G无线信道验证和测试的空白。

Different from 3G/4G channels,5G channels have 3D spatial characteristics due to the use of the Massive MIMO technique.Therefore,it is necessary to investigate the verification methods of 5G Massive MIMO channels,which is the key to multi-antenna performance testing of 5G base stations.For the verification and test of the 5G Massive MIMO channel,its generation and test system are first introduced.Then,using the PN correlation sequence and taking PDP as the evaluation index,the verification method of the multipath number,power and delay of the 5G Massive MIMO channel is studied.Subsequently,based on the vector network analyzer,a multipath angle verification method for the 5G Massive MIMO channel is proposed.Based on the above,a wireless channel verification and test method for 5G Massive MIMO performance evaluation are formed.The proposed method achieves the purpose of verifying the accuracy of the 5G Massive MIMO channel and fills the gap in the verification and testing of the 5G wireless channel.
