matlab 在信号分析处理及其应用signal and proce(matlab in signal analysis and its application to deal with signal and proce)

MATLAB及在电子信息课程中的应用，感觉很有用.(MATLAB and in the course of electronic information, I feel useful)

The advantage of static controllers is in their simple structure, however, their performance is not good. Therefore, in fact, the fundamental fuzzy controller is often combined with conventional ones (e.g., PID controller) to create a dynamic fuzzy controller to have higher control quality. there is an PIDFuzzycontroler example

对一个mat文件中的数据进行滤波后再进行奇异值分解降噪。奇异值降噪方法参考附件中的文献(filtering the data with medfilter and SVD(singular value decomposition))

波阈值去噪，比较了软阈值，硬阈值及当今各种阈值计算方法和阈值函数处理方法的性能，通过信噪比及均方差的比较，得出各种的算法的优劣(Wave threshold denoising compared soft threshold and hard threshold and the current calculation method and the various thresholds threshold function processing performance of the method by SNR and mean square deviation of the comparison, the pros and cons of various algorithms)

在一个图像块中调整两个(或多个) DCT系数的相对大小。将描述一个使用数字图像作为载体的系统。在编码处理中，发送者将载体图像分成8×8的像素块，每一块只精确地编码一个秘密信息位。嵌入过程开始时，首先伪随机地选择一个图像块bi，用它对第i个消息比特进行编码。令Bi=D{bi}为DCT变换后的图像块。 在通信开始前，发送者和接收者必须对嵌入过程中使用的两个DCT系数的位置达成一致，让我们用(u1,v1)和(u2,v2)来表示这两个索引。这两个系数应该相应于余弦变换的中频，确保信息保存在信号的重要部位(从而使嵌入信息不容易因JPEG压缩而完全丢失 (abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwx)

混合动力汽车控制策略模型，可通过设置接口实现对被控对象的控制(Hybrid vehicle control strategy model that can be controlled by setting the object' s interface for control)

文献“Sparse Representation based Fisher Discrimination Dictionary”及其对应的matlab代码，稀疏学习是目前非常流行的方法，希望对大家有所帮助(a paper named Sparse Representation based Fisher Discrimination Dictionary and its matlab code)

为了实现DOA和时延的联合估计,提出了一个无线通信中高分辨率的联合角度和时延估计方法,该方法不需要对参数进行搜索,利用空时矩阵的特征向量和特征值分别估计DOA和时延,通过特征值和特征向量的对应关系,估计的参数可以自动实现配对, 只要各路径信号的DOA和时延不同时接近此方法都可以适用,与JADE-MUSIC,JADE-ESPRIT和SI-JADE算法相比,该算法具有较好的鲁棒性和较小的估计误差。仿真结果证明了该算法的有效性。 (In order to achieve the joint estimation of DOA and delay, proposed a wireless communications joint angle and high resolution delay estimation method, the method does not require parameters to search using the space-time matrix eigenvectors and eigenvalues​ ​ , respectively, and the estimated DOA delay, by the correspondence between eigenvalues ​ ​ and eigenvectors, the estimated parameters can be automatically paired DOA and delay of each path as long as the signal is not close to this same method can be applied, with the JADE-MUSIC, JADE-ESPRIT and SI-JADE algorithm, the algorithm has better robustness and smaller estimation error. The simulation results show the effectiveness of the algorithm.)
