无线信道模拟器的研究与设计

Research and design of wireless channel simulator

近年来人们对移动通信的需求极速增长,促进了无线通信技术的蓬勃发展。目前无线通信系统的验证工作主要靠外场实地试验,对环境要求苛刻。无线信道模拟器能够使得在室内进行系统验证成为可能,其可以大大地提高系统验证的效率。文章研究并设计了一种基于FPGA和Simulink的无线信道模拟器的实现方案,通过对比计算机仿真与硬件仿真的结果,验证了方法的有效性。

In recent years,people’s demand for mobile communication has increased rapidly,which has led to the vigorous development of wireless communication technology.At present,the verification of wireless communication system relies on outside field tests,which require strict environment condition.The wireless channel simulator can make system verification in the lab possible,which can greatly improve the efficiency of system verification.In this paper,a scheme of wireless channel simulator based on FPGA and simulink solution was learned and designed.By comparing the results of computer simulation and hardware simulation,the validity of the method was verified.
