Sammanfattning
In this paper, we develop superfast approximative algorithms for
the computationally efficient implementation of the recent Iterative
Adaptive Approach (IAA) spectral estimate. The proposed
methods are based on rewriting the IAA algorithm using suitable
Gohberg-Semencul representations, solving the resulting linear
systems of equations using the preconditioned conjugate gradient
method, where a novel preconditioning is applied using an incomplete
factorization of the Toeplitz matrix. Numerical simulations
illustrate the efficiency of the proposed algorithm.
