基于混沌的JPG图像加密系统，使用MATLAB实现的，带界面，适用于课程设计(JPG image encryption based on chaotic system using MATLAB to achieve, with the interface for curriculum design)

LBP特征提取的MATLAB实现，其getmapping.m定义了lbp三种不同的模式，而lbp.m则是lbp的实现，当然它只是简单的整幅图像的lbp变换（没有分区域），其中很巧妙地运用了整体移动的方法计算lbp值。(LBP feature extraction MATLAB, which getmapping.m defines lbp three different modes, while lbp.m is lbp realize, of course, it simply lbp transform the whole image (no sub-region), which is very clever use of the method of calculating the overall mobile lbp value.)

基于S函数编写了自抗扰控制器中的跟踪微分器（TD）,扩张状态观测器（ESO）,非线性反馈（NLSEF），并在Simulink环境下搭建ADRC，完成对方波的跟踪，简单好用(S function based on written ADRC in tracking differentiator (TD), extended state observer (ESO), non-linear feedback (NLSEF), and built ADRC in the Simulink environment, complete track the other waves, simple and easy use)

混频向量自回归模型，用于处理混频数据，可以避免同频数据导致的信息缺失(mixfrequency VAR)

说明：  OFDM是将高速串行数据分成成百上千路并行数据,并分别对不同的载频进行调制,这种并行传输体制大大扩展了符号的脉冲宽度,提高了抗多径衰落的性能。同时,在传统的频分复用方法中,各子载波之间的频谱互不重叠,频谱利用率较低。而采用OFDM技术,一个OFDM符号之内包括多个经过调制的子载波的合成信号,每个子载波在频谱上相互重叠,这些频谱在整个符号周期内满足正交性,因而在接受端可以保证无失真恢复,从而大大提高频谱利用率。(OFDM divides high-speed serial data into hundreds of parallel data channels and modulates different carrier frequency separately. This parallel transmission system greatly expands the pulse width of symbols and improves the performance of anti-multipath fading. At the same time, in the traditional method of Frequency Division multiplexing, the spectrum between the sub-carriers does not overlap each other, the spectrum utilization ratio is low. In the case of OFDM, an OFDM symbol consists of multiple modulated sub-carriers, each of which overlaps in the spectrum, which is orthogonal throughout the symbol period, thus, no distortion recovery can be ensured at the receiving end, thus greatly improving the spectrum utilization ratio.)
