RUDIN-SHAPIRO WAVELET TRANSFORMS AND THE CONSTRUCTION OF EQUIANGULAR TIGHT FRAMES

Recently, in an article by the first author et al, a new class of compactly supported wavelets, based on the well known Rudin-Shapiro polynomials, have been constructed. Here, by applying these wavelets, we provide a method for constructing equiangular tight frames (ETFs) for some finite dimensional Hilbert spaces
