Annotation:

A method of parametric adaptations turbocodes under the effect of jamming, that give rise to uncertainties in the decoding process of turbocodes. The essence of the method lies in the choice of parameters adaptive turbocode using a priori and a posteriori information decoder turbocode by minimizing the average risk. The proposed results can be used to improve the reliability of data transmission systems, which operate under the action of powerful jamming.

Key words:

turbocodes, adaptation, decoding algorithms
