Paper Abstract
As is well known, wavelet filterbanks in general do not allow for shift invariance due to the downsampling operation. In this paper we discuss the design of a tight frame symmetric filterbank {h0, h1, h2, h3}, with the requirement that h2 and h1 be identical within a shift by one sample, or we seek h2 (n) = h1(n-1). This results in the wavelets ψ1 and ψ2 related as ψ2(t) = ψ1(t - 1/2).
