Title
(EN) DEVICE FOR CHANNEL EQUALISATION AND DECODING
(FR) DISPOSITIF D'EGALISATION ET DE DECODAGE DE CANAL
Abstract
(EN)
The invention concerns a device for channel equalisation and decoding of a received signal, in the form of successive observations representing a coded signal made up of encoded data corresponding to a convolutional coding of source data, and transmitted in a transmitting channel, comprising means (41) for consolidating a sequence of at least two consecutive observations, in the form of an observation vector, said observations being selected such that they all depend on a common set of at least two source data, and processing means (42), supplied by said observation vector and delivering a decoded vector, consisting of an estimation of source data forming said set of source data.
(FR)
L'invention concerne un dispositif d'égalisation et de decodage de canal d'un signal reçu, présenté sous la forme d'observations successives représentatives d'un signal codé formé de données codées correspondant à un codage convolutif de données source, et transmis dans un canal de transmission, comprenant des moyens (41) de regroupement d'une séquence d'au moins deux observations consécutives, sous la forme d'un vecteur d'observations, lesdites observations étant choisies de façon qu'elles dépendent toutes d'un même ensemble d'au moins deux données source, et des moyens (43) de traitement, alimenté par ledit vecteur d'observations et délivrant un vecteur décodé, formé d'une estimation de données source formant ledit ensemble de données source.
