M- Band Interpolatory Wavelet Packets
Zhang Xin-jing · Journal of Mathematical Research and Exposition · 2004
In this paper, we present a construction of M-band interpolatory wavelet packets. M-band interpolatory wavelet packets is a sequence space spanned by dilation translates of a iterate function sequence obtained by a cardinal interpolation function. The wavelet packets provide a finer decomposition for a given signal and give a better localization. Hence approximated sampling theorem in the wavelet packets space is obtained.
