摘要
OFDM是一种多载波调制方式。为建立一个完整的系统仿真模型,通常需要考虑其中的关键技术:调制方式、保护间隔以及信道模型的建立。论文在研究上述技术的基础上,建立了基于MATLAB的系统仿真模型,着重分析了OFDM系统在不同信道环境下的传输特性,对进一步深入研究OFDM技术具有一定的指导作用。
OFDM is one of the Multicarrier modulation technologies, To build an integrated system model, modulation manners, guard interval and channel model are usually considered. Upon the analysis of these key technologies, simulations of OFDM base-band system model based on MATLAB are presented. Finally the characteristic of transmission under varied channels are described. This is of guide significance for the further research of OFDM technology.
