1.对染噪doppler信号进行小波包3层分解：分解层次j=1,2时

function Noisysig = GWNoisy(data,sigma)
%  GWNoisy- Addition of a Gaussian White Noise
%  Usage
%    Noisysig = GWNoisy(sig,sigma)
%  Inputs
%    sig        Input signal
%    sigma   s.d for additive Gaussian White Noise
%  Outputs
%    Noisysig    1-d signal
%

n=length(data);
Noise=GWN(n,sigma);
Noisysig=Noise+data;
