Description: 根据OFDM的基本原理, 利用MATLAB编写
OFDM系统仿真的程序,通过分步执行,能够比较清
楚地了解OFDM实现的整个过程,熟悉每一步变化
的数据特征。对掌握OFDM的原理和熟悉MATLAB
仿真都是非常重要的,仿真的最后给出了该OFDM
系统仿真的误码率。其中qpskmod.m 为QPSK调制
的函数 qpskdemod.m 为QPSK解调的函数 comb.m
为产生加性高斯白噪声的函数 giins.m 为往信号中
插入保护间隔的函数 girem.m 为从接收信号中去除
保护间隔的函数。这部分函数分别由相应的子程序
实现,文中没有给出源代码。-Orthogonalfrequencydivisionmultiplexing (OFDM) isamulti 2carrierbroadbandmodulation
