基于OFDM技术的通信系统设计与仿真
Design and Simulation of Communication System Based on OFDM Technology
摘要
Abstract
In order to solve the problem of frequency selective fading in modern mobile communication,or thogonal frequency division multiplexing (OFDM) is proposed.The technology has the advantages of high efficiency,anti interference,high frequency utilization and so on.Through the construction of OFDM communication system model,the simulation is carried out by MATLAB programming language,and the influence of different channel interpolation methods on signal is compared before and after adding window function and cyclic prefix.The experimental results show that the DFT interpolation method is feasible and efficient for the improvement of signal quality in OFDM communication system.关键词
