Abstract
This paper proposes a novel gradient algorithm for complex adaptive IIR notch filters with constrained poles and zeros. We applied the algorithm to a high-order adaptive notch filter structure with matrix form, which consists of first-order filters. Computer simulation shows that the convergence speed of the adaptive algorithm is faster than the conventional ones, moreover the stability of the resulted adaptive filters is sure.
