通过matlab仿真分析了QAM 调制方式在AWGN信道下的误比特性能(By matlab simulation analysis of QAM modulation in AWGN channel BER performance)

本项目主要工作是对提供图片与库中图片进行颜色和纹理两方面的匹配。其中，颜色匹配直接用基于颜色RGB的直方图匹配，纹理匹配则是通过小波变换转换成频域值，然后用Canny算子计算总和，最后得到图片的纹理图进行匹配(The main work of this project is to match the colors and textures to provide pictures and picture in the library. Among them, the direct use of color matching based on the color RGB histogram matching, texture matching wavelet transform converted into frequency domain values​ ​ , calculate the sum of the Canny operator, and finally get the picture of the texture map to match )

A simulink model ued for Fourier transformation analysis. It allows the user to select the harmonics number.

说明：  网上大多数matlab代码跑出来的结果不准确，在原有基础上改了一下，但只能在证据之间不产生冲突情况下使用(Most of the MATLAB codes on the Internet run out of inaccurate results. They have been modified on the original basis, but can only be used in cases where there is no conflict between the evidences.)

此例程为配套书籍的第六章例题6-6的相对应代码，功能为计算雷达回波信号的多谱勒时频谱，编程环境为matlab。(This routine supporting books Chapter Example 6-6 corresponding code function for calculating the radar echo signal Doppler spectrum for Matlab programming environment.)

非均匀傅里叶变换是传统傅里叶变换的扩展,它尤其适合于适合于非均匀采样数据或要计算 任意频率的频谱.(Nonuniform Fourier Transform (NUFT) is the extension of traditional Fourier transform,it is particularly used for nonuniform-sampled data analysis and calculating arbitrary spectral.)
