Simulation BCH in communication channel with different SNR

里面有灰色预测模型的matlab程序，只需输入数据即可，调试成功，可运行。(There are gray prediction model matlab program, you can simply enter the data, debugging success, can be run.)

此代码包含常见的线性调频雷达信号的去斜处理，时域上与参考信号进行混频时选择的起始时刻，以及加窗的注意事项(This code contains the common chirp radar signals dechirping, starting time of the selected mixing with the reference signal in the time domain, and precautions windowed)

完整的NMF算法资料，有说明文件，有代码，也有运行案例。是非常不错的学习NMF的资料。(This is a NMF complete algorithm, including information, documentation, and the code, and also run case. This is a very good learning information of NMF.)

Mfcc 提取语音特征参数 可以分辨出不同情感(Mfcc speech feature extraction can distinguish between different emotions)

脉搏测量仪代码 主要功能是显示脉搏跳动次数，测试时间和上一次测试次数(Pulse measuring instrument code The main function is to display the number of pulse, the test of time and the last number of tests)

正交匹配追踪法实现1-D信号压缩传感，测量数M>=K*log(N/K),K是稀疏度,N信号长度,可以近乎完全重构(Orthogonal Matching Pursuit)

利用该matlab程序对近红外光谱进行MSC等预处理，很好用。(The use of near-infrared spectroscopy matlab program pretreated MSC so easy to use.)

根据学生两次考试成绩的数据来预测学生是否能被大学录取，用逻辑斯蒂回归算法实现，分别执行梯度下降算法、随机梯度下降算法、牛顿法(According student test scores twice to predict whether the student can be admitted to universities, implemented in logistic regression algorithm.)
