个人编写的计算单次声发射信号的时域特征参数的程序，用以计算声发射信号的幅值，上升时间，持续时间，计数，能量等(The matlab program is used for calculating the characteristics of a burst AE signal in Time domian, such as amplitude, rise time, duration, count, energy and so on.)

说明：  matlab提供了rgb2gray的函数，但是如果gray想要换成rgb，就要自己写了。(matlab function rgb2gray provided, but if you want gray into rgb, should write their own.)

说明：  今天好心情，搞了几个小程序，大家分享一下(A good mood today, engaging in several small programs, we share)

3G里使用的Spreading技术演示仿真。用于教学演示的Matlab模型。A demo of spreading code generation and modulation used in 3G.(3G Lane Spreading the use of simulation technology demonstration. Teaching Demonstration for the Matlab model. A demo of spreading code generation and modulat ion used in 3G.)

这是考虑光信道色散，对输入信号的影响，结果仿真了功率谱密度(This is to consider chromatic dispersion of the optical channel, the input signal, the results of simulation of the power spectral density)

说明：  基于灰度直方图，对图像的纹理特征进行提取，根据灰度共生矩阵得到的四个纹理描述子。(Histogram based on image texture features were extracted, according to the four GLCM texture descriptors obtained.)

WPanalysis Function for wavelet processing

说明：  交织编码信噪比的matlab仿真实现，用matlab进行通信系统中的交织实现，并测量snr并画出曲线(matlab simulation of interlever snr)
