generate a normal sequence from rayleigh distribution

通信系统matlab仿真可能用到的程序，比如高斯噪声，功率算法，并联与直联系统的转换等(Telecommunication system may be used in matlab simulation , for instance gaussian noise, power algorithm, parallel and straight league system conversion etc)

hilbert-huang 变换分析一段脉搏波 运行maihht即可(hilbert- KE3 transform a pulse wave can run maihht)

多元线性回归分析预测法针对概率论中的回归预测做了研究，推荐各位大侠阅读(Multiple linear regression analysis prediction for the probability of regression to do the research, recommended reading you heroes)

爬山法提取窗户，源数据是地面激光扫描点云(Hill climbing method to extract the windows, the source data is a ground-based laser scanning point cloud)

利用MATLAB实现了卷积码编码和维特比译码的整个过程，实现了软判决和硬判决的对比。(Using MATLAB realize the whole process of convolution code and Viterbi decoding to achieve a contrast soft decision and hard decision.)

说明：  VMD代码，该程序对信号进行经验模式分解，可以用于故障信号处理，还可以与很对方法结合。如，排列熵，emd,vmd,等，包含VMD、EMD、EEMD工具箱，可用于变分模态分解、EMD以及EEMD谐波检测对对比分析(VMD code, the program for empirical mode decomposition of signals, can be used for fault signal processing, can also be combined with a very good method. For example, permutation entropy, EMD, VMD, etc., including VMD, EMD, EEMD toolbox, can be used for comparative analysis of variational mode decomposition, EMD and EEMD harmonic detection pairs)

Matlab_曲面插值和拟合，dajie可以看看(something about Matlab_b-spline)

用不同的函数求得阈值进行消噪，希望对大家有用(The threshold denoising obtained with the different functions the hope that useful)
