说明：  8，16，64进制的qam 星座图转换，MATLAB程序(8,16,64 qam constellation hex conversion, MATLAB program)

一副图可视为一个矩阵，将其分成上线两部分，然后用矩阵的合并实现两个图简单拼接。目的主要使新手熟悉matlab的这种图形处理方法。(A diagram can be regarded as a matrix, to be divided into on-line in two parts, and then use the matrix of the merger of two diagrams simple splicing. The main purpose of the novice familiar with Matlab this graphical approach.)

可以运行的PID模型，可以运行的PID模型可以运行的PID模型(Can run the PID model, the PID model can run the PID model can be run)

截取一段音频信号作为输入信号，分别通过低通，高通和带通滤波器，比较滤波效果。(Interception of an audio signal as an input signal, respectively, through a low pass, high pass and band-pass filter, compare filtering effect.)

时频分析，用于信号的时频分析，短时傅里叶变换、小波、脊线提取、一些信号的生成，等等。(Time-frequency analysis, time-frequency analysis for signal, short time Fourier transform, wavelet ridge line extraction, generate some signal, and so on.)

最大流问题的算法，思路清晰，很值得收藏。大家赶快下载(Algorithm for maximum flow problem is clearly thought worthy of collection. U.S. soon to download)

最大似然和最大后验概率算法描述，比较性能，仿真分析(Maximum likelihood and maximum a posteriori probability algorithm description, comparative performance, simulation analysis)

这是一些关于学习matlab 的资料，我认为比较重要对于matlab的初学者，上传以下希望和各位朋友分享一下资源，还望多多交流！(This is some information on learning matlab, I think the more important for matlab beginner, upload the following hopes and all our friends to share resources, but also hope that more exchanges!)

根据信号不同的特点，自适应的构造小波基，实现与信号的最佳匹配。(According to the different characteristics of signal, the structure of the adaptive wavelet base, to achieve the best match with the signal. )

说明：  用matlab实现ARQ 有具体代码和注释 已验证 可运行(Realization of ARQ Verification with MATLAB)
