基于WARP的无线通信实验研究平台设计

摘要

针对无线通信研究与教学实验软硬件分离导致的实验结果不准确与实验效果不直观问题,设计实现了基于Matlab与Wireless Open Access Research Platform(WARP)的可视化实验研究平台.该平台基于WARPLAB环境,并以802.11 n物理层标准为原型实现了2×2 MIMO-OFDM传输系统.基于该平台可以进行MIMO无线通信、信源编解码、实测信道参数与OFDM无线通信理论等研究教学实验活动.%Aiming at the problem that the experimental results are inaccurate and non-intuitive, which are brought about by the separation of the wireless communication research from the hardware and software of the teaching experiment, a visualized experimental research platform is designed and realized on the basis of Matlab and WARP(wireless open access research platform).The platform is based on WARPLAB environment, and by using the 802.11n physical layer standard as the prototype, 2×2 MIMO-OFDM transmission system is achieved.Based on this platform, the research, teaching and experimental activities can be carried out for the MIMO wireless communication, the signal source coding and decoding, the real measurement of the signal channel parameters, the OFDM wireless communication theory, etc.
