image-processing

说明：  matlab 做图讲义，介绍如何使用matlab自带的命令画一维，二维，三维图形。(matlab study sourse)

利用此程序，可以对图片的直方图特征进行提取，进而进行图片的分类，并统计出分类的正确率。(With this program, you can picture the extraction, and then classify pictures and statistics of the correct rate of classification.)

对于频率估计有效的研究方法 其中有matlab的原始的程序(Frequency estimation matlab)

IMPORTANCE SAMPLING sIGNAL PROCESSING

对肌电信号进行简单的时频分析，包括RMS，肌电积分值，动态中值频率，近似熵，边际谱熵等(HHT Marginal Spectrum Entropy )

QPSK信号通过瑞利衰落信道后的误比特率和误符号率，并与AWGN信道下的误比特率和误符号率进行对比。其中，多普勒频移为 100Hz，经过矩形脉冲成形后的抽样时间间隔为1/800000s。(The QPSK signal harms the bit rate after the Rayleigh fading channel and harms the mark rate, and harms the bit rate with the AWGN channel under and harms the mark rate to carry on the contrast. And, the Doppler shift is 100Hz, after undergoing the square pulse forming the sampling time gap is 1/800000s. )

一个matlab gui小代码，用于数据进制的转换(A small code matlab gui for data hex conversion)

说明：  变模态分解（EMD）的代码，适用于对非平稳非线性信号的分解，分解后得到多个IMF和一个残基。(The code of variable modal decomposition (EMD) is suitable for the decomposition of non-stationary and nonlinear signals, and after decomposition, multiple IMFs and one residue are obtained.)

other technique for LDPC

三相三线制两电平APF数学模型的MATLAB编程实现，输入为三桥臂的开关函数，输出为三相电流和直流侧电压(Three-phase three-wire APF system for the two-level mathematical model of the MATLAB programming)
