摘要 随着4G的到来,OFDM系统在生活中有着越来越重要的作用。论述了OFDM通信系统的仿真设计,其中包括编码、调制、IFFT、同步、解调和解码等模块,重点研究并论述了基于训练符号和循环前缀的OFDM系统的时频同步和相位同步的算法及其性能,介绍了SCME信道的特性,并完成了对OFDM系统在AWGN信道和SCME信道下的仿真及其性能分析,与理论性能相符。 With the advent of 4G,OFDM system has an increasingly important role in the life.This paper discusses the simulation design of OFDM communication system,including coding,modulation,IFFT,synchronization,demodulation and decoding modules,and studies and describes the time-frequency synchronization and phase synchronization algorithm of OFDM system and its performances based on training symbol and cyclic prefix. The characteristics of SCME channel are introduced, and the simulation and performance analysis for OFDM system in AWGN channel and SCME channel are implemented. The simulation and analysis results show that the practical performances are consistent with the theoretical performances.
