Abstract :
The authors analyze the adaptive infinite-impulse-response (IIR) filter algorithm, i.e., the output error algorithm. Based on the averaging SPR condition (B.D.O. Anderson et al., 1986 and E. Bai et al., 1988), the authors present two stable output error adaptive IIR filter algorithms and their realizations. These algorithms can more readily satisfy stability conditions and are easier to realize. The adaptive IIR filter is stable with a high convergence rate. It has a greater tracking ability than the HARF (hyperstability adaptive recursive filter)
