摘要
正交频分复用被看作是第四代移动通信的核心技术之一,在高速数据传输中得到了广泛的应用。本文介绍了OFDM的基本原理,给出OFDM系统的基本框架,并基于Systemview建立了OFDM系统的仿真模型。分析了采用编码和交织的系统性能并给出了仿真结果。为进一步研究OFDM系统性能提供了一个通用的平台。
OFDM is regarded as one of the core technologies in 4G mobile communication system and has been broadly used in the transmission of high-speed data. The Basic principles of OFDM and the basic frame of OFDM system are presented in the paper .And the simulation of the OFDM system using Systemview is also presented. The system performance under channel code and interleaving are analysed and results of simulation are given.
