BOC调制，原始信号扩频之后与方波相乘，使得频谱分裂，抗干扰能力很强！(BOC modulation, spread spectrum, after the original signal multiplied with the square wave, making the spectrum division, a strong anti-interference ability!)

基于第三代通讯wimax核心编码ofdm编码的matlab性能仿真(based on the third generation telecommunications wimax core coding ofdm coding Matlab Performance Simulation)

此程序是LMFnlsq2.rar主程序调用的一个函数，此函数不可或缺，需要联合使用。(This program is LMFnlsq2. Rar main program calls a function, this function is indispensable, need to use.)

说明：  SFA算法的matlab实现，不是使用工具箱的那种，纯编程，望支持(The algorithm of SFA, not use the tool box function, use laugage of matlab.)

此函数实现含噪语音的信噪比的计算，以最小帧算法为基础。(Implementation of this function of the signal to noise ratio of noisy speech has calculated that, with the smallest frame-based algorithm.)

由信道信号的复数值解调对应的二进制序列由信道信号的复数值找出对应的二进制序列。方法如下：由信道值， ％％求出该值与星座图中所有点的距离，找出距离最小的点，该点对应的 ％％二进制序列及为该信道对应的解调结果。 (Channel signal by the complex demodulation value corresponding to the binary sequence by the complex channel signals to identify the corresponding binary numerical sequence. As follows: by the channel value, the value obtained with the constellation diagram of all points of distance, find the smallest distance between points, the points of the corresponding binary sequence and the corresponding channel demodulation results.)

Voice activity detection using zero crossing criterion.

power_transfo3wdn.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_transfo3wdn.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)
