Blind equalization algorithm for 16QAM signal

利用MATLAB绘制等温线，以湖南省为例，绘制了省界，97县的位置以及等温线。(plot temperature contour through MATLAB.)

计算序列的自相关函数,绘制信号xn的自功率谱幅频曲线,绘制信号yn的自功率谱幅频曲线,计算互谱函数(Calculating the autocorrelation function of the sequence, drawn from the power spectrum of the signal xn amplitude-frequency curve, drawn from the power spectrum of the amplitude-frequency curve signal yn calculated cross-spectral function)

这是加权网络中节点强度和权重都是幂率分布的模型。(This is a node-weighted network strength and weight distribution are the model of power.)

说明：  通信信号的调制信息包含在信号的瞬时幅度、相位、频率的变化之中，不同的信号其频谱也呈现不同的特征，通过提取瞬时幅度、相位、频率以及频谱的参数统计特征，可以识别不同的通信信号。通常是利用对瞬时幅度、瞬时相位，瞬时频率和信号功率谱进行某种变换而得到可以明显区分各种信号的特征参数。(Communication signal modulation information is contained in the signal instantaneous amplitude, phase, frequency changes, the spectrum of different signals also show different characteristics, by extracting the instantaneous amplitude, phase, frequency and statistical characteristics of the parameters of the spectrum, you can identify different communication signals. Usually by the use of instantaneous amplitude, instantaneous phase, instantaneous frequency and signal power spectrum a transformation which can be clearly distinguished by the characteristic parameters of various signals.)

实现信号的eemd分析，呈现其波动趋势，是继小波分析之后的又一信号分析利器(Emd achieve signal analysis, showing its fluctuation, wavelet analysis is the second after another signal analysis tool)

此程序主要是通过使用小波达到图像文件压缩的目的，可以比较不同的小波函数和压缩次解压缩后图像文件的差异，注意图像是二维的处理时使用二维的小波函数(This process is mainly through the use of wavelet compression to achieve the purpose of image files, you can compare different wavelet functions and extract the compressed time difference after the image file, pay attention to the handling of two-dimensional image is the use of two-dimensional wavelet function)

数字信号处理实现滤波器的功能，此程序中有几个滤波器的实现(Digital signal processing filter function, this procedure several filter)
