本程序通过matlab实现图片的RGB域到LAB域的转换，本程序包含测试程序，可以完全跑通，敬请放心使用。(This procedure achieved by matlab image RGB domain to the domain of LAB, this program includes testing procedures, can be completely run through, please rest assured that use.)

实现单相交流信号锁相功能，单相锁相环，matlab simulink程序。(matlab simulink single phase )

matlab实现语音信号计算其信噪比，其中包括一个原始语音文件。(matlab，calculate the SNR of a speech)

说明：  BP神经网络的语音特征信号分类算法，采用归一化算法及变学习率学习算法(BP neural network speech characteristic signal classification algorithm, using a normalization algorithm and the learning algorithm learning rate change)

matlab的频谱矫正程序以及实例，可用于搭配滤波器产生需要的信号(err)

最小频移键控（Minimum Shift Keying，MSK）是一种具有连续相位和最小频偏的数字调制技术。MSK的突出优点是信号具有恒定的包络和信号的相位连续性，频带利用率高，信号的功率谱在主瓣外衰减较快，这就使得它对邻波道干扰小。(MSK (Minimum Shift Keying) is a continuous phase and the minimum deviation of the digital modulation techniques. Outstanding advantage of MSK signals have constant envelope and continuous phase signals, high bandwidth efficiency and the signal power spectrum decreases rapidly outside the main lobe, this makes it a small adjacent channel interference.)
