Frequency-Synthesis-by-Phase-Lock

说明：  it is the matlab model for simulation of the class bchopper with full details of parametrs

基于matlab的8-3编码器，使用模块实现编码，并进行封装(8-3 matlab-based encoder module using coding and packaging)

一个圆周卷积的代码~调用形式为y=juanji(h,x1,M) 其中，h和x1为输入，h为滤波器系数，x1为输入采样信号，输出为y,M为输入信号x1的长度。(A circular convolution of the code to call the form of y = juanji (h, x1, M) of them, h, and x1 for the input, h for the filter coefficient, x1 sampling input signals, output y, M for the input signal x1 length.)

通过matlab代码实现PCA算法程序设计步骤： 包括1、去均值 2、计算协方差矩阵及其特征值和 qZHBpQ 特征向量 3、计算协方差矩阵的特征值大于阈值的个数以及 ixDqskB值 4、降序排列特征值，编译通过达到很高的性能。(PCA algorithm program realization by matlab code design steps include: 1, 2 to the mean, covariance matrix and its eigenvalues and eigenvectors qZHBpQ 3, calculate the covariance matrix of eigenvalues greater than the number of threshold values, and only 4 ixDqskB, in descending order eigenvalues, compiled by achieving high performance.)

线性调频信号的分数阶傅里叶变换，完整可用。分数阶傅里叶变换采用Pei采样算法，在傅里叶域呈现宽带特性的线性调频信号，在分数阶域呈现窄带特征。(The fractional Fourier transform of linear frequency modulation signal, available. fractional Fourier transform using Pei s sampling algorithm, in Fourier domain present broadband characteristics of linear frequency modulation signal, the fractional domain present narrowband feature. )

Matlab读取 Excel 表格数据的源程序，希望有用！(Matlab read Excel spreadsheet data source, hope useful!)

This code extract the Accelerometer calibration coefficients for an IMU.

matlab simulation example

对信号进行EEMD分解，比原先的EMD效果更好，能够分解出较好的本征模函数(EEMD the signal decomposition, works better than the original EMD, better able to factor out the intrinsic mode function)

说明：  主要是RD CS 算法，针对点目标的仿真结果，比较清晰(RDA CSAchengxiangsuanfa)
