基于Simulink的OFDM通信系统仿真

Simulating Communication System of OFDM in Simulink

正交频分复用(OFDM)是第四代移动通信的核心技术,它是实现多媒体业务发展的基础.讨论了如何利用Simulink进行OFDM系统仿真,并给出了具体的仿真模型.利用仿真模型得到OFDM差错性能分析结果,通过对结果的分析,提出了改善性能的方法.

Orthogonal frequency division multiplexing（OFDM） is a core technique in 4 G[1], which is the basis of the development of multimedia service. A method for simulation of OFDM in Simulink is discussed in detail and a model of simulation is given. By utilizing the model, we can get the results of error rate performance of OFDM system. By contrast, a method for improving the performance of system is proposed.
