Research on a Simulation System of OFDM Using SIMULINK

介绍了OFDM基本原理,基于SIMULINK详细讨论了如何构建一个完整的OFDM动态仿真系统。通过仿真分析了信道特性,无信道估计和LS信道估计对OFDM系统性能的影响。结果表明:此仿真系统能够很好地模拟OFDM传输系统,为进一步深入研究OFDM通信系统提供了便利。

After describing the basic structure of OFDM scheme,we discussed how to design a simulation model of OFDM based on SIMULINK.At last,channel characteristic,without channel estimation and LS channel estimation,which will affect the performance of OFDM system,are analyzed by simulation.The simulation results show that the proposed model to the transmission system of OFDM is good,and this model also provides convenience for researching OFDM communication system in the future.
