Abstract:The existence problem of tight multiple cycled frames is studied. The translation operator Sk(τ)is defined for the space L2[-π,π]of all square-integrable periodic complex-valued functions, and the periodic affine functions are constructed from the periodic refinable functions and periodic complex sequences. We put forward a sufficient condition for the existence of tight multiple cycled frames by virtue of the unitary extension principle, the time-frequency analysis method and frame multiresolution analysis. The tight frames are constructed by the unitary extension principle. Moreover, the compactly supported periodic tight frames are obtained.
