Title
(EN) QUANTIZATION METHOD FOR ITERATIVE DECODER IN COMMUNICATION SYSTEM
(FR) PROCEDE DE QUANTIFICATION POUR DECODEUR A ITERATION D'UN SYSTEME DE TELECOMMUNICATIONS
Abstract
(EN)
A quantization method for an iterative decoder. In the quantization method, received signal levels are equally divided into predetermined intervals within a range 2n (n is a positive integer) times greater than the transmission signal level range of the transmitter, and the level of the input signal received in each period is quantized.
(FR)
La présente invention concerne un procédé de quantification destiné à un décodeur à itération. Ce procédé de quantification consiste à prendre les niveaux du signal reçu et à les diviser en intervalles définis dans une plage 2n fois plus grande que la plage des niveaux du signal de l'émetteur, 'n' étant un entier positif. Il ne reste plus qu'à quantifier le niveau du signal d'entrée reçu dans chaque période.
