多元线性回归分析，基于matlab的开发演示(Multiple linear regression analysis based on matlab development demonstrates)

说明：  本程序主要是为初学者提供，里面介绍了怎样用MATlab观察一个信号的波形 星座图 频谱 等(this program is to provide beginners. on the inside with what MATlab observation of a signal waveform constellation spectrum)

神经网络的matlab代码，欢迎亲们使用(The bpp neural network)

deep learning code it helpful the begainer in deep learning

数字脉冲宽度调制，将输入的数字信号转换为对应占空比的模拟波形(Digital pulse width modulation, the digital signal is converted to the corresponding input of the duty cycle of the analog waveform)

Image processing: MAP and DCT implementation in Matlab

这个是希尔伯特黄变换自己改的EMD经验模态分解仿真程序。(This is the Hilbert-Huang Transform own reform empirical mode decomposition EMD simulation program.)

frequency expander. Matlab code for expander.When x is a vector, this function adds L-1 after each element of x. When x is a matrix, each column of it treated as vector and expanded L fold. SQUARE-ROOT RAISED-COSINE PULSE: h=sr_cos_p(N,L,alpha) This function generates a square-root raised-cosine pulse of length N+1. There are L samples per symbol period. alpha is the roll-off factor.

这个是霍夫曼编码的问题，要求输入只含有ABCD的四句话，且每句8个字符的长度，然后求出四个字符每个的概率，然后当成权值计算霍夫曼编码，我的这个程序已经实现了输入、概率统计、计算出霍夫曼编码存在了bian[]这个数组中(hoffuman decoding)

Mathematica 环境下GNSS导航信号体制中的BOC调制、BPSK调制的功率谱计算及频谱图绘制程序，相关函数计算(GNSS navigation signal system in the BOC Mathematica modulation, BPSK modulation of the power spectrum calculation and spectral mapping procedures, the calculation of the correlation function)
