随着3G与物联网等新领域的不断拓展与应用,OFDM准“4G”技术成为当下无线通信的研究重点。本文利用SCILAB仿真平台中模块搭建及模块替换方式,设计实现一种可视化OFDM通信仿真系统,为不同搭建方式下的生成OFDM系统进行性能对比分析提供可能性,优化系统并为日后硬件设计做好准备。 With the constant development and application of new fields such as 3G and Internet of Things, the OFDM “4G” technology has become the research focus of the current wireless communications. In this paper, we design and implement a visualized OFDM communication simulation system based on the module building and module replacement in the SCILAB simulation platform, and provide the possibility for comparative analysis of the performance of the generated OFDM system under different structures, optimize the system and prepare for future hardware design .
