计算hurst指数 主程序 利用经典的RS分析法计算分形H指数(calculate hurst parameter)

快速傅立叶变换,快速傅立叶反变换实现和基本思想。(Fast Fourier Transform, Fast Fourier inverse transform to achieve and the basic idea.)

说明：  小波插值（全小波插值，小波双线性插值，小波双三次插值及其改进）放大图像，提高图像的分辨率；对插值图像做质量评价（峰值信噪比PSNR；均方信噪比SNR）(Wavelet interpolation (full wavelet interpolation, wavelet bilinear interpolation, cubic interpolation and improved method) to enlarge the image and improve image resolution assesse the interpolation image (peak signal to noise ratio PSNR mean square signal to noise ratio SNR))

电力线通信多径信道模型-Manfred Zimmermann模型，多径效应的传递函数H(f)可以用N条传输路径的叠加以及含有频率f、延时τ、距离d的方程来表示： H(f)=∑g_i *A(f,d_i )*e^(-j2πfτ_i ) 式中，i 为路径号， g_i为路径 i的加权系数(包含了传输系数和反射系数的作用)，A(f,d_i )为衰耗，其大小由长度、频率决定，τ_i是每条路径上的延时。 (Powerline Communication multipath channel model-Manfred Zimmermann model)

此程序是用二分法求非线性方程在一定精度下的近似解以及迭代次数，这是通用程序(This program is the dichotomy of nonlinear equations in the approximate solution under certain precision and number of iterations, which is a universal program)
