Fast iterative methods for solving Toeplitz-plus-Hankel least squares problems
Electronic transactions on numerical analysis, Tome 2 (1994), pp. 154-170
In this paper, we consider the impulse responses of the linear-phase filter whose characteristics are determined on the basis of an observed time series, not on a prior specification.
