一个二阶中心插值滤波器（DDF2）的目标跟踪仿真实例。(a second center interpolation filter (DDF2) target tracking simulation example.)

用MATLAB写的，用Prim算法找出图中的最小支撑树，文件中有例子，有计算的结果，一看便懂。(Written in MATLAB, with the minimum support tree in the Prim algorithm to find a figure, file example, with the result of calculation, a see will understand.)

说明：  采用弧长法通过matlab编程求解非线性方程数值解(MATLAB code solving 1D nonlinear equation with the arch-length method.)

这是一个接收机系统，详细的给出了信号的产生，调制，发射，接收，解调等环境，很好的例子(This is a receiver system, the signal is given in detail the generation, modulation, transmit, receive, demodulation and other environment, a good example)

结合boosting与神经网络方法相结合的分类方法，效果好，识别率高(Combining boosting and neural network approach for robust classification, effective with high recognition rate)

干扰对齐中，两种经典的分布式算法（Max_SINR与Min_MLI）对比matlab代码(Interference alignment, the two classical distributed algorithm (Max_SINR and Min_MLI) contrast matlab code)

传统的DOA估计算法，如MUSIC、ESPRIT算法，都是在假设信号没有相干的情况下求解的，一旦信源信号具有相干性，估计性能会急速下降，所以提出了空间平滑的算法，解决相干信号的波达估计！(The traditional DOA algorithms, such as MUSIC, ESPRIT algorithm, is under the assumption that the signal is not coherent case solving, once the source signal with coherence, estimation performance will fall, so put forward spatial smoothing algorithm, to solve the coherent signal estimation of direction of arrival!)
