说明：  用matlab写的一个关于最大期望算法EM实现(Using matlab to write an EM algorithm on the greatest hope to achieve)

背景差法检测运动的机动车辆，汽车已被检测的图图像边缘提取预处理和,可以直接使用。 (Background difference method for detecting movement of motor vehicles, the car has been on the detecction of image edge extraction pretreatment and complete source code can be directly used by the test )

The DSI method is basically a modified SLM method. The additional aspect of the DSI method is to add M-bits dummy sequences to the original sequence in order to reduce the PAPR. Where, the dummy bits are inserted at the end of the data sequence (y). Next, after IFFT, we select the M-DSI sequence having the lowest PAPR.

利用DFT实现两轮信号相位差计算，包含谐波信号污染，白噪声信号污染分析(Phase difference between two signals to achieve the use of DFT calculations, the signal containing harmonics pollution, contamination white noise signal analysis)

通过16个接收水听器组成线列阵，分别给出各个阵元接收信号，可实现 时域、频域等信号到达角判别(A linear array composed of 16 receiving hydrophones can be used to distinguish the angle of arrival of signals.)

说明：  递归图（reecurrence plots），从相空间重构时间序列的matlab程序，(recurrence plots recostitution matlab code)

vedic multiplication

给出BCH编码和译码的原理 以及解决方案，特别是仿真的一种解决方案，值得参考。(BCH coding and decoding given the principle, as well as solutions, in particular the simulation of a solution, it is also useful.)

支持向量机用于回归，在MATLAB里实现的。方便好用(Support vector machines for regression, implemented in MATLAB in. Is easy to use)
