matlab下，使用dspbuilder生成的信号生成模块的源码(Matlab, the use of the signals generated dspbuilder generation module source)

运用帧间差法检测，基于kalman滤波的目标跟踪。(Use of the inter-frame difference method detection, based kalman filtering target tracking.)

绘制庞加莱截面图的程序。先通过solveLor.m来求出一系列点，然后代入Poincare_section 程序绘制庞加莱截面。 通过观察Poincare截面上截点的情况可以判断 是否发生混沌：当Poincare截面上有且只有一个不动点或少数离散点时，运动是周期的；当Poincare截面上是一封闭曲线时，运动是准周期的 当Poincare截面上是一些成片的具有分形结构的密集点时，运动便是混沌。 (Poincare section drawing program. First obtained by solveLor.m to a series of points, and then drawn into the program Poincare Poincare section. By observing the situation on the Poincare section cut points can determine whether chaos occurs: When there is only one fixed point or a few discrete points on the Poincare section, the motion is periodic When is a closed curve on the Poincare section, the motion is quasi- When is the point of having a dense fractal structure on some stretches of the Poincare section, the motion is chaotic period.)

说明：  一种分簇算法，适合用于数据聚类，将相似的点集合到一个簇内。(Its a new method of clustering,useing this clustering algorithm ,you can obtain a cluster which is stable )

对于目标跟踪在WSN中的应用，采用二项式拟合方式的目标位置预测源码(WSN mobile targets tracking)

简单的OFDM仿真，采用QPSK调制，有串并转换，保护间隔，fft/ifft等(Simple OFDM simulation using QPSK modulation, there are serial to parallel conversion, guard interval, fft/ifft etc.)
