中文说明：添加噪声处理，比较了软阈值，硬阈值及当今各种阈值计算方法,能量熵的计算，可直接计算得到多重分形谱,供做算法研究人员参考，一些自适应信号处理的算法。
English Description：
Add noise to deal with, the soft thresholding, hard threshold and the current threshold calculation method, energy entropy calculation, direct calculation to obtain the multifractal spectrum, for the reference algorithm researchers, some adaptive signal processing algorithms.
