蔡氏混沌电路的仿真,混沌同步中常用同步方法的仿真，基于蔡氏混沌电路(cai chaos control)

随机信号功率谱分析 (1) 生成信号，被淹没在在噪声中； (2) 试用周期图法估计信号的功率谱； (3) 选用不同窗，使用修正周期图法估计信号的功率谱； (4) 对一段语音信号，使用LD算法估计其功率谱； (5) 详细列出功率谱估计的步骤和原理。 (power spectral analys)

ecently, more and more attention is paid to reversible data hiding (RDH) in encrypted images, since it maintains the excellent property that the original cover can be losslessly recovered after embedded data is extracted while protecting the image content’s confidentiality. All previous methods embed data by reversibly

该算法可以直接实现，程序不需要修改且有详细的程序解释(The algorithm can directly implement the program and there is no need to modify the procedure explained in detail)

数字调制2FSK信号的调制，利用matlab仿真(2FSK digital modulation signal modulation, the use of matlab simulation)

说明：  一种基于正交频分复用系统，存在定时偏差时的系统性能代码(based on orthogonal frequency division multiplexing system, there are regular deviation of system performance code)

LLC仿真 自己搭的可以运行， 但不是变频闭环控制，是开环定频的(LLC simulation can run itself, but not frequency conversion closed loop control, it is open-loop constant frequency.)

说明：  实现蚁群算法，实现蚁群算法的MATLAB程序。只要输入城市坐标就行(The realization of ant colony algorithm, ant colony algorithm to achieve the MATLAB program. Just enter the city coordinates on the line)

马克维茨有效边界检验，分为有无风险利率和有无风险利率两类(Markowitz efficient frontier inspection, into whether the interest rate risk interest rate risk and the availability of two types of)
