Application of two-channel prediction filtering to the recursive filter design problem
Leroy C. Pusey · IEEE Transactions on Acoustics Speech and Signal Processing · 1983
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.
