(FR) APPAREIL ET PROCÉDÉ POUR BOUCLE À VERROUILLAGE DE PHASE ENTIÈREMENT NUMÉRIQUE
Abstract
(EN)
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may receive an otw signal that is associated with low-path pass information and transmission data. The apparatus may apply a cost function and an update function to the otw signal prior to sending the otw signal to an oscillator. The apparatus may determine a correction factor for use in estimating a gain of the oscillator based at least in part on an output of the update function.
(FR)
Un aspect de l'invention concerne un procédé, un support lisible par ordinateur et un appareil. L'appareil peut recevoir un signal OTW qui est associé à des informations de passage à trajet bas et à des données de transmission. L'appareil peut appliquer une fonction de coût et une fonction de mise à jour au signal OTW avant d'envoyer le signal OTW à un oscillateur. L'appareil peut déterminer un facteur de correction destiné à être utilisé dans l'estimation d'un gain de l'oscillateur sur la base, au moins en partie, d'une sortie de la fonction de mise à jour.
