光纤Bragg光栅的基模（LP01）的有效折射率和谐振波长的计算测试程序，欢迎拍砖

这是实现随机信号模拟用户数据流，值得一看哦(this is random signal simulation user data flow, an eye-catcher oh)

判决反馈滤波器的工作频率受限于电路速度，本程序通过并行信号处理，可以使其工作于任意高的频率。(The speed of DFE is limited by the timing of circuit. This program speed up the DFE by parallel signal processing.)

Matlab Programming Tutorial

说明：  该程序可以用来计算齿轮啮合的时变啮合刚度(Time-varying meshing stiffness of gears)

在瑞利衰落和高斯白噪声下qam调制对于不同信噪比的误码率(bit error rate of the Qam modulation in Rayleigh fading and Gaussian white noise for different signal to noise ratio)

MATLAB模拟的电磁学时域有限差分法的配套程序(MATLAB simulation of electromagnetic hours FDTD matching program)

基于消除趋势项法的振动信号预处理研究.在MATLAB环境中对基于消除趋势项法的振动信号预处理的实例仿真分析。有 最小二乘法去趋势；正弦信号去趋势和滑动平均法等(In the MATLAB environment to eliminate the instance of the trend of the vibration signal preprocessing based on simulation analysis based on the signal preprocessing to eliminate the vibration of the trend of law. Least squares method to the trend sinusoidal signal to the trend and moving average method)

用赫夫曼树进行编码和解码的相关操作，支持字符串的加密和解密(the procedure was wrote for huffman code ,which can be uesd to encode sting)
