Abstract
In this paper we present a comparison of the tracking characteristics of Lattice based complex adaptive IIR notch filter (L-CANF) using new adaptive algorithm and Direct from based complex adaptive notch IIR notch filter (D-CANF) using simplified gradient descent adaptive algorithm for different step size parameters. Three cases are investigated, i.e., linear chirp, quadratic chirp and randomly-hoping frequency input complex signals buried complex zero mean white Gaussian noise. Computer simulations shows the better tracking performance of L-CANF based on new adaptive algorithm over D-CANF based on simplified gradient descent algorithm.
