Patent

CA 2083749

The maximum likelihood sequence estimation apparatus decodes a digital data signal. The apparatus includes: sampling device to perform sampling and output a received signal by sampling pulses having a constant time interval T and N different sampling phases, an operation device to operate a branch metric of the received signal sampled by the N different sampling phases, and a device to perform maximum likelihood sequence estimation of the branch metric.

L'invention est un appareil d'estimation de maximum de vraisemblance utilisé pour décoder des signaux de données numériques. Cet appareil comprend un dispositif d'échantillonnage de signaux qui échantillonne des impulsions ayant une période constante T et N phases d'échantillonnage différentes, un dispositif de branchement du signal reçu selon ces N phases et un dispositif d'estimation du maximum de vraisemblance du branchement.
