Abstract
(EN)
Embodiments of the present invention provide a method for decoding a signal. The method comprises: decoding a received signal by using a predetermined decoding scheme, and obtaining an estimation of a transmitted signal on the basis of the decoding result; obtaining an estimation of channel noise by using the correlation of the channel noise; subtracting the obtained estimation of the channel noise from the received signal, so as to obtain a modified received signal; and decoding the modified received signal by using the predetermined decoding scheme, so as to obtain a decoded signal. The embodiments of the present invention also provide a device for decoding a signal, and a storage device.

Selon certains modes de réalisation, la présente invention concerne un procédé de décodage d'une image. Le procédé consiste à : décoder un signal reçu à l'aide d'un schéma de décodage prédéterminé, et obtenir une estimation d'un signal transmis sur la base du résultat de décodage; obtenir une estimation de bruit de canal à l'aide de la corrélation du bruit de canal; soustraire l'estimation obtenue du bruit de canal à partir du signal reçu, de façon à obtenir un signal reçu modifié; et décoder le signal reçu modifié à l'aide du schéma de décodage prédéterminé, de façon à obtenir un signal décodé. Les modes de réalisation de la présente invention concernent également un dispositif de décodage d'un signal, et un dispositif de stockage.
