Abstract
This paper presents an analysis technique for an adaptive ARMA lattice filter based on the CORDIC algorithm. The proposed technique brings a theoretical convergence analysis, which facilitates an efficient ASIC design of the ARMA lattice filter. Although the proposed technique is dedicated to filters using a special arithmetic unit (CORDIC processor), we can apply it to popular multiplier-based filters through slight modifications. Consequently, we can utilize the proposed technique for many applications in the signal processing.
