摘　　要：为培养学生在通信原理课程中进行创新性实验的能力,设计了一种基于LabVIEW的2×2 MIMO通信系统,系统包括信号形成、信号调制解调、时空分组编码译码和滤波器等模块。软件LabVIEW提供了大量的函数和工具用于数据采集、分析、显示和存储,将传统仪器的操作面板通过计算机显示,同时LabVIEW利用电子设计自动化技术完成信号调理与处理。2×2 MIMO通信系统只需利用计算机和通用软件无线电平台(USRP),将传统仪器的信号调理与处理功能交由计算机完成,实现硬件功能软件化,降低了进行通信原理创新性实验的难度,为进一步创新实验教学提供了良好的平台。In order to cultivate students’ability of innovative experiments in communication principles course,a 2×2 MIMO communication system based on LabVIEW was designed.The system includes modules of signal formation,signal modulation and demodulation,space-time block coding and filter.LabVIEW platform provides large number of functions and tools for data acquisition,analysis,display and storage,and displays the operation panel of the traditional instrument through the computer.At the same time,LabVIEW completes signal adjustment and processing by using the electronic design automation technology.This 2×2 MIMO communication system only needs the computer and software radio platform to complete the signal conditioning and processing functions of traditional instruments by computer,which can implement the hardware function and software,reduce the difficulty of innovative experiments on communication principles and provide help for further innovative experiments.
