ldpc在BSN信道下的性能仿真，程序较简单，但可以运行，仅供参考(ldpc in the performance of BSN channel simulation, the program is relatively simple, but it can run for reference only)

watermarking using dwt

支持向量机的多分类问题，主要是将其分成了5类(Support Vector Machine)

OFDM过程的代码，简单实用，包括梳状导频和块状导频( the code of OFDM process, simple and practical，Including comb pilot and block pilot)

PSO 工具箱，粒子群优化测试，有具体的使用方法。调试简单，易懂。(Particle Swarm Optimization)

matlab在有限元中的应用，平面常应变三节点单元，注解清晰，应用方便。(matlab in finite element applications, three-node constant strain plane unit, well commented, easy application. )

Matlab necessary notes

说明：  设计产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，使用矩形窗设计不同特性的数字滤波器对信号进行滤波处理，分析所设计滤波器(画出了频率特性曲线)，并对信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，同时设计出了一个友好的人机交互界面。(Designed to produce a continuous signal, including low frequency, medium frequency, high frequency components, its sampling, spectral analysis, using rectangular windows of different characteristics of digital filter design the signal filtering, analysis of the designed filter (to draw the frequency characteristic curve), and signal filtering, to draw the filtered signal in time domain waveforms and frequency spectrum, and filtering the signal before and after comparison, the mean time, a friendly interactive interface.)
