ABSTRACT:
A method of improving turboencoding by re-encoding erroneous information and subtracting their contribution at the input of the turboencoder. The subtraction of this contribution remedies the lack of convergence or convergence towards erroneous solutions observed in certain turbodecoding configurations. The method also applies to parallel concatenation turbodecoding, to serial concatenation turbodecoding, or to block turbodecoding. Different operations result according to the type of feedback envisaged.
