#21 Answer: Wavelet sampling (WD 6.1 #24)

Your problem has a name: the initialisation of DWT. There are some
papers dealing with this problem. For example:

[Abr.,Fla.'94] P. Abry, P. Flandrin, "On the Initialisation of the
Discrete Wavelet Transform Algorithms", IEEE Signal
Processing Letters, vol.1, no.2, February 1994;

[Del.,Jud.'95] B. Delyon, A. Juditsky, "Estimating Wavelet
Coefficients", in "Wavelets and Statistics", Editors: A.Antoniadis,
G.Oppenheim , Springer-Verlag, 1995,

[Rio.,Duh.'92] O.Rioul, P. Duhamel, "Fast Algorithms for Discrete and
Continuous Wavelet Transforms", IEEE Trans. on Inf. Theory, vol. 38,
no.2, March 1992,

[She.'92] M.J.Shensa, "The Discrete Wavelet Transform: Weding the A
Trous and Mallat Algorithms", IEEE Trans. on Signal
Proc. vol. 40, no.10, October 1992,

[Xia.,Kuo.,Zha.'94] X.G.Xia, C.C.J.Kuo, Z.Zhang, "Wavelet Coefficient
Computation with Optimal Prefiltering", IEEE Trans. On Signal
Proc. Vol. 42, no.8, Aug. 1994.

I work myself on this subject, and I can be found by e-mail
at the address isar@ee.utt.ro, for a change of information .

Best wishes.
