Abstract
A new adaptive infinite impulse response (IIR) filtering algorithm for noisy input-output systems is proposed. The variances of the input and output measurement noise, which specifies the source of the noise-induced bias in the standard least-squares estimate, are computed using extra delayed noisy input measurements. Since good estimates of the noise variances are obtained in a quicker manner, the proposed adaptive algorithm achieves a faster rate of convergence
