Abstract :
The purpose of this paper is to construct a new two-dimensional (2-D) adaptive joint-process IIR filter with the generalized lattice structure. This filter is an IIR lattice filter with the restricted feedback structure, but the backward prediction error fields for every stage, like FIR lattice filter, are orthogonal which produce fast convergence. More importantly it can borrow both FIR and IIR features and simultaneously holds the well-known merits of lattice structure
