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