CA 2238330

Methods and apparatuses for evaluating expressions used, for example, in convolutional decoders are described. By arranging digital logic elements in a manner designed to minimize the number of additions performed while evaluating hypothetical bit sequences, decoder performance is improved. Bit metrics and combinations thereof are first determined and supplied to a multiplexor. The multiplexor can then be controlled to output the selected one of the bit metrics or combinations thereof which is to be added to an accumulated path metric.

L'invention porte sur des procédés et appareils permettant d'évaluer des expressions utilisées par exemple dans des décodeurs à convolution. En disposant les éléments logiques numériques de manière à réduire le nombre des additions effectuées lors de l'évaluation des séquences binaires hypothétiques, il est possible d'améliorer les performances du décodeur. Des métriques binaires et leurs combinaisons sont tout d'abord élaborées puis transmises à un multiplexeur qui peut alors être commandé pour émettre l'une des métriques binaires ou ses combinaisons qui sont ensuite ajoutées à la métrique des cheminements accumulés.
