通过学习LDPC编译码原理，编写了LDPC码的编译码程序。通过此程序可以更好的实现LDPC码的仿真(in this passage we have write the program of edcoded and decoded of LDPC code.through it we can undersatand LDPC more.)

LAS file reading. this is useful for reading of LiDAR data LAS file.this is very useful code.

OFDM系统接收机移除循环前缀，代码本人亲自撰写，如有疑问可讨论之(the rx_move_cyclic_prefix function of the OFDM system)

基于梯度下降法的SVM的实现。适合初学者(Gradient descent method to achieve SVM. Suitable for the news.)

说明：  本算法是基于蝙蝠优化算法BA优化SVM，可以大大提高VMD的分类准确率，提高优化时间。(This algorithm is based on bat optimization algorithm BA to optimize SVM, which can greatly improve the classification accuracy of VMD and improve the optimization time.)

function named myresize and scale_image to resize and scale images in matlab

matlab 演奏卡农 各种给力 好听啊(matlab demo and most unusual national air. Is to force a good listen)

关于SVM toolbox的详细使用说明，使读者可以很快的会使用SVM matlab工具箱(About SVM toolbox for details on these, so that readers can quickly use the SVM matlab toolbox)

说明：  半监督学习matlab代码程序，训练集 测试集代码，优化半监督svm 朴素贝叶斯 等等(matlab code program, training set test set code, optimized semi-supervised svm naive Bayes, etc.)

基于参数和非参数的多种频谱检测算法研究及仿真结果分析。(Based on the parameters and non-parametric multi-spectrum detection algorithm research and analysis of simulation results.)
