摘　　要：在5G多模终端多天线系统设计中,需要进行阵列参数估计,提出一种基于多输入多输出(Multi input multi output,MIMO)的5G多模终端多天线系统设计方法,进行5G多模终端多天线传感阵元联合参数估计,提高对目标检测和识别能力.采用多分辨的近场源分布阵列构建5G多模终端多天线的传感阵元目标阵列分布节点模型,采用多传感器联合跟踪识别方法构建5G多模终端多天线系统的传输信道模型,结合MIMO系统的窄带分布源特性,建立5G多模终端多天线系统的接收端信号检测模型,采用匹配滤波器进行5G多模终端多天线输出的阵列优化模式和检测滤波设计,提高对5G多模终端多天线输出信号的波束集成能力,采用自适应波束形成算法,实现5G多模终端多天线系统的多波束集成分布式传输设计,在MIMO系统中实现5G多模终端多天线通信和信号传输.仿真结果表明,采用该方法进行5G多模终端多天线系统设计的信道均衡性较好,输出稳定性较强,5G多模终端多天线输出的误码率较低.In the design of a 5 G multi-mode terminal multi-antenna system,array parameters need to be estimated. A design method for this system based on multi-input and multi-output(Multi input multi output,MIMO)is proposed.The joint parameter estimation of 5 G multimode terminal multi-antenna sensor array elements is carried out to improve the ability of target detection and recognition.The sensor element array distributed node model of 5 G multi-mode terminal multi-antenna sensor array is constructed by using a multi-resolution near-field source distribution array.The transmission channel model of 5 G multimode terminal multi-antenna systems is carried out by using a multi-sensor joint tracking and identification method.Combining with the narrow-band distribution source characteristic of MIMO system,the receiver signal detection model of 5 G multi-mode terminal multi-antenna system is established. In order to improve the beam integration ability of the multi-antenna output signal of 5 G multimode terminal,the adaptive beamforming algorithm is adopted to design the optimized array mode and detection filter for the multi-antenna output of 5 G multimode terminal by using matched filter.The design of multi-beam integrated distributed transmission for 5 G multi-mode terminal multiantenna system is realized,and its communication and signal transmission are realized in the MIMO system.The simulation results show that the channel equalization and output stability of 5 G multimode terminal multi-antenna system designed by this method are good,and the BER of 5 G multi-mode terminal multi-antenna system is low.
