Abstract: We discuss wavelet-oriented ideas to construct bases of
algebraic polynomials. In particular, the splitting in the
frequency domain is extended in order to define wavelet packets.

Keywords: polynomial wavelets, wavelet packets, Chebyshev polynomials, orthogonal bases, generalized Chebyshev shift
