Abstract
Convolutional codes are decoded by calculating, for uncoded and coded symbols, a first and/or second item of reliability information (&Lgr; and &Lgr; respectively). The item of reliability information is representative of the probability that the considered n uncoded or coded symbol is equal to a value i of the symbol set, under the condition that a specific sequence of received coded symbols is present. An approximate expression is proposed for calculating the second item of reliability information.
