Adaptive digital filters are currently used in many communication systems for echo cancellation, channel equalization, and adaptive noise cancellation. Most practical applications presently use adaptive finite impulse response (FIR) digital filters because they are well behaved in terms of convergence and stability properties. The authors present an adaptive algorithm that operates with a parallel-form infinite impulse response (IIR) filter structure for applications in which an FIR filter requires too much computation. The algorithm is derived mathematically and the results of computer experiments are presented to demonstrate its performance.
