Abstract :
Fast and numerically stable algorithm for calculation of turbo-equalizer coefficients of serial modem, based on the Levinson-Durbin method and considering standard specificity of inverted parameter matrix: band type, hermiticity, toeplitz and positive definiteness, and its special correlation with a vector of absolute terms, is proposed. Results of accuracy and numerical stability of algorithm were obtained by modeling.
