NormNoise

Estimates noise level, Normalize signal to noise level 1

Calling Sequence

[y,coef] = NormNoise(x,qmf)

Parameters

Inputs:

x :

1-d signal

qmf :

quadrature mirror filter

Outputs:

y :

1-d signal, scaled so wavelet coefficients at finest level have median absolute deviation 1.

coef :

estimation of 1/sigma

Description

This is required pre-processing to use any of the DeNoising tools on naturally-occurring data.
