Abstract

This paper presents a CORDIC-based architecture for adaptive lattice filters. The proposed filter architecture consists of simple components: a CORDIC processor and an adder, so that it can be implemented with a reduced amount of hardware. Moreover, the proposed architecture is useful for ASIC design because it has a regular, modular, and locally-connected structure. In addition, since our architecture is effective even in case of ARMA lattice filters, it can be utilized for many applications in the digital signal processing field.
