Title
(EN) APPARATUS AND METHOD FOR REMOVING COMMON PHASE ERROR IN A DVB-T/H RECEIVER
(FR) APPAREIL ET PROCÉDÉ POUR ÉLIMINER UNE ERREUR DE PHASE COMMUNE DANS UN RÉCEPTEUR DVB-T/H
Abstract
(EN)
A receiver is a Digital Video Broadcasting-Terrestrial/Handheld (DVB -T/H) receiver. The DVB-T/H receiver comprises a phase error corrector and a channel estimation and equalization element. The phase error corrector rotates a signal in accordance with an estimate of a phase error, e.g., CPE, which is determined as a function of channel state information (CSI) provided by the channel estimation and equalization element.
(FR)
L'invention concerne un récepteur portable terrestre de diffusion vidéo numérique (DVB -T/H), qui comprend un correcteur d'erreur de phase et un élément d'estmiation et d'égalisation de canal. Le correcteur d'erreur de phase fait tourner un signal en fonction d'une estimation d'une erreur de phase, par exemple une CPE, qui est déterminée comme fonction d'une information d'état de canal (CSI) fournie par l'élément d'estmation et d'égalisation de canal.
