Abstract In this paper, we study Daubechies periodized wavelet packets (DPWP) and give a necessary condition for it. Also, some properties of DPWP are discussed. Further, we give an estimate for the approximation error related to DPWP. Finally, we use the thresholding technique to study compression errors.
