分数阶傅里叶变换资料,非常有用的信号处理变换工具(Document of chirp Flouier，which is very useful for signal processing and transformation.)

这些资料都是有关数学建模所用的SPPS软件的资料，希望对大家有帮助。(These data are used for mathematical modeling of SPPS software information, we want to help.)

说明：  matlab实现数字调频与解调，并进行结果显示。(matlab digital FM demodulation, and display the results.)

说明：  利用改进的蚁群算法来实现对路径规划，找到一条最优路径(Ant colony algorithm path planning)

用MATLAB实现的离散系统灰色PID位置跟中系统(MATLAB implementation of the discrete-time systems with PID position with the system of gray)

主要是研究信号、系统与系统响应，用matlab实现，对连续信号的采样以及卷积定理的验证以及相关的幅频特性等(is to study signal system and the system response using Matlab realized, the continuous signal sampling and convolution theorem certification and the associated frequency characteristics)

You can call your own C or Fortran subroutines from MATLAB as if they were built-in functions. MATLAB callable C and Fortran programs are referred to as MEX-files. MEX-files are dynamically linked subroutines that the MATLAB interpreter can automatically load and execute.

说明：  bp神经网络的模型训练与测试，并判断模型的可靠性。(Bp neural network model training and testing, and judge the reliability of the model.)

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.)
