perbaikan terhadap STC untuk pergeseran15 dB

系统辨识作业，仿真比较OE模型 ARMAX模型 和ARX模型的便是效果，内涵ppt。(System identification operation, the simulation model compared OE and ARX model ARMAX model is the effect, meaning ppt.)

Particle swarm optimization code

here is program is related to optimization method, gui, regression, graph.

说明：  同时正交分解，也是对MP的改进，实现信号的稀疏分解(At the same time orthogonal decomposition, also MP for improvement, and the signal is sparse decomposition)

在matlab环境下，变程实现了用全局直方图均衡化对图像做反差改善(In matlab environment, the change process to achieve the overall situation with the image histogram equalization contrast to do to improve)

statistical methods in order to extract image texture descriptors. In particular, we will focus on the Co-occurrence matrices and the Energy filters (Laws filters). They are well-known texture descriptors, fast and easy to implement and provide good results that could be used in a posterior step to perform image segmentation and object recognition.(statistical methods in order to extract image texture descriptors.

对图像进行直方图均衡的matlab程序示例。里面有图像处理前后直方图对比，代码简单易懂。(Histogram equalization)

对比了基于二阶和高阶统计量的DOA 估计算法性能，仿真结果表明，基于高阶统计量的DOA 估计算法具有更好的性能(Compare the performance of DOA estimation algorithm based on second-order and higher-order statistics, simulation results show better performance DOA estimation algorithm based on higher order statistics)

OMP算法的本质思想是：以贪婪迭代的方法选择D的列，使得在每次迭代的过程中所选择的列与当前冗余向量最大程度的相关，从原始信号向量中减去相关部分并反复迭代，只到迭代次数达到稀疏度K，停止迭代。(OMP compressed sensing )
