卡尔曼滤波在仿真中的应用，低于跟踪目标有很大的作用(NNAD applied to multi-target tracking, a great help for filtering, and fusion technology)

mimo-ofdm系统中产生相关mimo衰落信道(produce relevant mimo mimo-ofdm fading channel system)

xwch_test.m是主测试文件；biaoji.mat存放滤波器系数；xiangweicha.m用FFT计算相位差。 仿真框架为： 1.标记信号和双音信号续接作为发送信号； 2.对双音中一个频率分量的相位做偏移，再经过一个低通滤波器（引入线性相位，模拟收发不能同步测量现象）后，作为收到的信号； 3.用一个检测信号对收发信号进行相关运算； 4.画出收发信号以及相关处理后的信号。找出相关信号的那个尖点，从而推算出收发双音信号0相位点； 5. 输入0相位点位置，计算相对相位差。(xwch_test.m is the main test file biaoji.mat store filter coefficients xiangweicha.m calculated using FFT phase difference. Simulation framework: 1. Mark signals and then as a two-tone signal continued to send signals 2. On a two-tone frequency components of the phase shift to do, and then through a low pass filter (the introduction of linear phase, simulation can not simultaneously send and receive measuring the phenomenon), the as received signal 3. using a detection signal of the transceiver signal correlation operation 4. draw send and receive signals and related processed signal. Correlated signal of the cusp, which calculate the two-tone signal transceiver 0 phase point 5. Enter 0 phase point position, calculate the relative phase difference.)

有源滤波器控制的一个example，供大家参考学习(Active filter control of a example, for your reference learning)

用两种方法对图像进行增强，并且对比增强后的效果。(image inhance)

在数学规划，尤其在数学建模中，很好用,可以参考(In mathematical programming, especially in mathematical modeling, easy to use, you can refer to)

emd工具箱，用经验模态分解时一定要安装的工具箱，解压后添加进toolbox里，setpath后，记得更新工具箱，就可以使用了，我是用来分解信号进行信号处理的(emd toolbox with a time of empirical mode decomposition must install kit, unpacked add toolbox, the post setpath, remember to update the toolbox, you can use, and I was used to decompose the signal for signal processing)

自己建的PMSM矢量控制仿真模型，该模型完全基于simulink基础库创建，没有用到powersystem模型库。(Vector control of PMSM to build their own simulation model, the model based entirely on the simulink based library to create, not used powersystem model library.)
