QAM modulation using matlab

doarima.m MATLAB script to do an ARIMA(p,d,q) analysis where d is set but P and q can be vectors of values you want to try. It produces AIC and FPE (final prediction error) values for comparing models. The AIC is different than the one computed by S+, but they both minimize on the same model for the arma22.dat simulated data.

如下亮度变换功能的函数：负片变换、对数变换、gamma变换、和对比度拉伸变换。(Brightness as a function of conversion functions: negative transformation, logarithmic transformation, gamma conversion, and contrast stretching transformation.)

仿真效果非常好，包含特征值与特征向量的提取、训练样本以及最后的识别，小波包分析提取振动信号中的特征频率。( Simulation of the effect is very good, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition, Wavelet packet analysis to extract vibration signal characteristic frequency.)

说明：  Matlab的数理统计工具箱是Matlab工具箱中较为简单的一个，其牵扯的数学知识是大家都很熟悉的数理统计(Matlab statistics toolbox of Matlab toolbox is a relatively simple, the mathematics involved is that we are familiar with the knowledge of mathematical statistics)
