1.本程序用 JDK+6.0 + Eclipse3.2 + MyEclipse5.0.1 + Designer_v6.0.1_win32_x86 开发 2.运行非常简单, a.选安装JDK b.在可执行程序(Jar)文件夹中双击ChatSystemServer_fat.jar,点击启动 c.双击ChatSystemClient_fat.jar点击登陆

在MATLAB上实现扩展的SCM信道模型 clc;clear; scmpar=scmparset; linkpar=linkparset(6); % 10 links %linkpar.MsVelocity=0; scmpar.NumMsElements=2; scmpar.NumBsElements=2; antpar=antparset; [H delays out]=scm(scmpar,linkpar,antpar); % Initialize the parameters NumLoop = 90;%帧长 carrier_count=80;%子载波个数 carriers=1:carrier_count; NumSubc = 128;%IFFT和FFT的点数 NumCP =8;%循环前缀 NT=20 ; %导频之间的间隔,块状导频 Np=ceil(NumLoop/NT)+1;%导频数 %加1的原因：使最后一列也是导频 delta_t = out.delta_t; f_sym = 3.84e6; % sample frequency osr = floor((1/f_sym)/scmpar.DelaySamplingInterval); % over sample rate ts = 1/(f_sym*osr); % sample time_step

本文就OFDM技术进行了较为详尽的分析,并对OFDM的传输特性进行了基于FFT算法实现的MATLAB软件模拟及模拟结果分析
