Wavepacket decomposition of a noisy signal, Best Basis analysis, Thresholding in Best Basis
out=ThreshWP(Noisy,sigma,Type,mult,D,qmf)
1-d Noisy signal, length(Noisy)= 2^J.
Standard deviation of additive Gaussian White Noise.
'S' for soft thresholding, 'H' for hard thresholding. Optional, Default=hard thresholding.
Multiplier of sigma to obtain the value of the threshold. Optional, Default = sqrt(2*log(n)), where n is the length of datas.
degree of finest frequency partition. Optional, D=J-3.
orthonormal quadrature mirror filter Optional, Default = Symmlet 4.
Estimate, obtained by applying thresholding on wavepackets coefficients.
