Title (EN) ANALOG VITERBI DECODER
(FR) DECODEUR ANALOGIQUE DE VITERBI
Abstract: front page image
(EN)An analog Viterbi decoder in which some signal processing such as branch metric calculation by a branch metric calculator (1) and processing of addition, comparison and selection by an ACS circuit (2) are realized by analog signal processing. Thus the number of elements is greatly decreased and a small-sized high-speed Viterbi decoder is realized.
(FR)Décodeur analogique de Viterbi effectuant de manière analogique un traitement de signaux tel que le calcul métrique de branchement à l'aide d'un calculateur métrique de branchement (1), et un traitement d'addition, comparaison et sélection à l'aide d'un circuit ACS (2). Cet agencement entraîne une forte réduction du nombre de composants, ce qui permet de réaliser un décodeur de Viterbi très rapide et de petites dimensions.
