Abstract :
This paper presents the lattice structure of a class of dyadic symmetric wavelets with integer coefficients. These wavelets are found by factorization of the maximally-flat halfband filter. The proposed lattice structure has modular structure and is very robust with respect to coefficient quantization. Moreover, the number of internal bit is low and the overall structure is suitable for VLSI implementation
