小波分析用的mallat算法，是一种经典的算法，其中一个算法对火车信号进行了分析，(Mallat used wavelet analysis algorithm is a classical algorithm, an algorithm which analyzes the signal to the train,)

Higher-Order Spectral Analysis (HOSA) Toolbox

本文章教你如何将海量数据导入到matlab工作空间，方法简单，易懂(This article will teach you how to import huge amounts of data into matlab workspace, simple, easy to understand)

ber performance of sc-fdma, we can consider awgn channel or multipath channel.

小波分解和重构小波分解和重构小波分解和重构小波分解和重构(thr=sigma*(2*lgN)1/2/lg(j+1) 用[x,xn]=wnoise(2,10,6) 产生噪声测试数据-The following is Part I of a of hard and soft threshold denoising matlab procedure is the following hardware and software, I made a threshold denoising matlab program: thr = sigma* (2* lgN) 1/2/lg (j+1) by [x, xn] = wnoise (2,10,6) noise test data)

采用matlab工作环境，利用Thompson Tau进行异常值剔除(Remove outliers from data using the Thompson Tau method.)

说明：  基于MATLAB的FIR带阻数字滤波器的设计 由于生物医学信号处理过程中易混入50Hz噪声的特点，本文利用程序设计法和FDATool设计法，设 计一带阻滤波器，并将设计的滤波器应用到一混和正弦信号，通过测试检验，该滤波器可以很好地消除50Hz的工 频干扰。(】To prevent the biomedical signals from being disturbed by 50Hz noise easily，the paper designs a bandstop digital filter by procedure and FDATool method．The filter is tested by a blended 81ne wave experimentally and the result shows that the filter can cancel the 50Hz noise very well．)

给出了信号压缩通常的变换-量化-编码函数。DHT函数为离散DHT变换，是FFT变换的近似，其正反变换相同，克服了FFT复系数不利于存储的缺点。LLMAX函数给出了某x序列在固定比特下的最佳量化输出。熵编码函数为霍夫曼编码。(Gives the signal compression usually transform- quantitative- coding function. DHT DHT discrete transform function, the FFT transform approximation, the same positive and negative transformation, overcoming complex FFT coefficient is not conducive to storage shortcomings. LLMAX function x is given a fixed bit sequence in the optimum quantized output. Entropy coding function as Huffman coding.)

说明：  使用分形维数来提取缺陷中的感兴趣区域，本科毕业设计程序(Used to extract the fractal dimension of defects in the region of interest, graduate design program)
