Differentiated estimation of independence of components of a casual vector

用AR模型和SIMIU功率谱模拟脉动风，在叠加平均风，得到风序列(SIMIU power spectrum with AR model and simulate the fluctuating wind , the average wind overlay, get wind sequence)

实现希尔伯特-黄变换的功能，并带有一段测试数据。希尔伯特-黄变换是使用EMD分解将信号分解为本征模态函数（IMF），然后求得IMF分量的瞬时频率。其对于非稳态和非线性信号具有优良的效果。(The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear.)

蚁群算法的matlab实现程序代码，经过本人实际验证，能够很好的解决一些问题(Ant colony algorithm matlab implementation program code, after I actually verified, can well solve some of the problems)

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)

利用matlab进行主成分分析，得到各个相关系数等(Principal component analysis using matlab to get the various correlation coefficients, etc.)

对原有数据进行排列，找到它所在位置，求出符合要求的最小值(The original data are arranged in a position to find it, find the minimum to meet the requirements)

matlab 与C混编，通过交替最小化方法求解乘性噪声模型，利用了shifting技术。(Written by H. Woo and S. Yun, the corresponding paper is "Alternating minimization algorithm for speckle reduction with a shifting technique")

可以建立预测分析模型，十分好用，可以处理光谱数据建模。(The prediction analysis model can be established, which is very easy to use and can handle the modeling of spectral data.)

UWB1000模块测试所得数据初步处理之后，已知锚点的坐标，可利用该文件里的程序解算标签三维位置。(After preliminary processing of data obtained from UWB1000 module test, the coordinates of anchor points are known, and the program in this file can be used to calculate the three-dimensional position of tags.)
