Abstract

This article presents the application of the CrossEntropy (CE) stopping criterion to Turbo Equalizer using the Maximum A Posteriori (MAP) algorithm. It is part of reducing computational complexities by decreasing the number of iterations of a turbo receiver. The proposed criterion CE initially for turbo codes is applicable for any type of turbo receiver. We consider here a turbo equalizer MAP of a severe channel that has five coefficients. The simulation results show that the resulting MAP-CE Turbo Equalizer provides the same performances as the Turbo Equalizer, which uses the absolute number of iterations.
