Application of two-channel prediction filtering to the recursive filter design problem

We consider the recursive filter design problem for the case where the numerator and denominator polynomials have the same order and represent the problem in the context of two-channel prediction filtering. A new method of solution is then obtained by applying Strand´s two-channel extension of the Burg scheme. The new method is shown to yield a stable recursive filter while providing an improvement in performance over previous linear methods.
