An Efficient Adaptive Cascade IIR Filter
نویسنده
چکیده
Among the various linear infinite impulse response (IIR) structures for adaptive filters, cascade IIR filters have advantages of easy stability monitoring and good sensitivity performance. However, their high cost for computing gradients is a problem. A novel technique of backpropagating the desired signal is proposed and then a cascade structure satisfying the requirements of this technique is developed, resulting in an efficient adaptive filter. It has been shown that equation-error formulation is just a special case of this backpropagation idea.

A step-by-step algorithm for enhancement of periodic signals that are highly corrupted by additive uncorrelated white gausian noise is proposed. In each adaptation step a new parallel second-order section is added to the previous filters. Every section has only one adjustable parameter, i.e., the center frequency of the self-tuning filter. The bandwidth and the convergence factor of each secti...
