摘要
The classical Shannon sampling theorem has been extended to wavelet subspaces by Walter, that is, a signal f(t) in certain wavelet subspace VJ(φ) for certain scaling function φ(t) can be exactly reconstructed by its samples f(k/2J). For signals not necessarily in wavelet subspaces, the sampling theorem is not true. In this article, we estimate the aliasing error in the sampling theorem for a general signal. An application for the aliasing error estimation in the computation of the wavelet transform coefficients by the Shensa algorithm is also discussed.
