Knowledge of the process noise covariance matrix is essential for the application of Kalman filtering. However, it is usually a difficult task to obtain an explicit expression of for large time varying systems. This paper looks at an adaptive Kalman filter method for dynamic harmonic state estimation and harmonic injection tracking.(Knowledge of the process noise covariance matrix is essential for the application of Kalm an filtering. However, it is usually a difficult task to obtain an expli cit for large expression of time varying system s. This paper looks at an adaptive Kalman filter method for dynamic estimation a harmonic state nd harmonic injection tracking.)

分形分析的R/S重标极差方法求Hurst指数(Fractal analysis of R/S rescaled range method for the Hurst exponent)

PAPR 迭代降低算法仿真，包含16QAM及QPSK优化前和优化后(Matlab simulation iterative PAPR Reduction for 16QAM QPSK)

说明：  扩展卡尔曼滤波，适用于多目标跟踪，里面还有一个子程序(Extended Kalman Filter)

对信号进傅里叶变换，得到振幅谱和相位谱，并可画出振幅谱和相位谱。(The signal into the Fourier transform, the amplitude spectrum and phase spectrum and amplitude spectrum and phase draw spectrum.)

说明：  个人搜集的matlab中各种函数功能的详介绍，按照字母分类，适合初学matlab的(Personal collection of matlab functions in a variety of functions, introduced in detail, in accordance with the letter classification, suitable for beginners of matlab)

LSB匹配算法的实现。目前大部分都是LSB替换算法，较新的图像LSB匹配算法的嵌入和恢复我没有在其它地方找到。因此，自己写了一个，可以作为毕业设计的内容。matlab编写，经过充分测试，可用。(Image LSB Matching Algorithm,implementated using matlab )

潜在狄利克雷分析(LDA)的matlab代码，实现对语义主题的分布估计，附有相应的使用说明文件，使用简单，效果不错。(Matlab code of potential Dirichlet Analysis (LDA) , the distribution of estimates of the semantic theme , accompanied by the appropriate use of documentation , easy to use , good results.)
