OFDM的MATLAB经典程序，可以实现有关OFDM的主要仿真，已经验证(OFDM classic procedures of MATLAB, you can achieve the main simulation of the OFDM, has been to verify)

用matlab采集语音，信号加噪去噪，以及fft变换(With Matlab acquisition Voice, the signal plus noise denoising, and fft transform)

用最速下降法求解多维函数的极值 function [x,minf]=minFD(f,x0,var,eps) 目标函数：f 初始点：x0 自变量向量：var 精度：eps 目标函数取最小值时的自变量值：x 目标函数的最小值：minf( With the steepest descent method for solving the multi-dimensional function of the extreme value function [x, minf] = minFD (f, x0, var, eps) target function: f Initial Point: x0 argument vector: var Accuracy: eps target function takes the minimum value of the independent variable values: x minimum target function: minf)
