自相关函数在噪声检测,识别和有用信号的提取中的应用(autocorrelation function of the noise detection, identification and extraction of the useful signal of)

matlab - mapping 4 bit image to 8 bit and 8 bit image to 4 bit

说明：  用matlab仿真实现ldpc编解码，BPSK调制, 测定误码率与信噪比的关系(Using matlab simulation to realize LDPC Encoding and decoding, BPSK modulation, and to determine the relationship between bit error rate and signal-to-noise ratio)

矩陣案例，主要是以matlab軟件來運算標準題型。(Matrix case, mainly matlab software to compute the standard questions.)

Effective math model of IPMSM with 2 output fuzzy logic controller as speed controller. Good for simulation results.

信号去噪的基本步骤： （1）信号的小波分解； （2）小波分解高频系数的阈值量化； （3）信号的小波重构。使用分解的低频系数以及阈值量化后的高频系数进行小波重构。 (The basic steps of signal denoising:( 1) of the wavelet decomposition of signals ( 2) the high frequency coefficients of wavelet decomposition threshold quantization ( 3) the signal wavelet reconstruction. Using the decomposition of the low frequency coefficient and threshold quantization the high-frequency coefficient after wavelet reconstruction.)

压缩包中的程序用于局部放电的模式识别，里面包含去噪，特征提取及模式识别程序。(Compressed package in the program for partial discharge pattern recognition, which contains denoising, feature extraction and pattern recognition procedures)

matlab function that is written in matlabbb

直方图均衡化是指将一幅图像的像素值均匀地分布在图像的各个区间上，从而是图像的视觉效果得到改善。(Histogram equalization is an image pixel values evenly distributed in various intervals in the image, which is to improve the image of the visual effects.)

helps to find the maximum entropy value to be optimised using PSO. Produces good results than ostu method
