Patent

CA 2665159

A method for performing symbol timing estimation is disclosed herein. In one approach, the method includes defining a search space in a plurality of estimated magnitudes of channel taps; defining a search window (SW-33) in the search space; and locating a symbol timing estimate index in the search space corresponding to a maximum value of an energy of the plurality of estimated magnitudes of channel taps within the search window (1660). A computer program product having code and a wireless communications apparatus for performing the method are also described herein.

L'invention concerne un procédé pour effectuer une estimation de temporisation de symboles. Selon une approche, le procédé comprend les étapes consistant à définir un espace de recherche dans une pluralité d'amplitudes estimées de dérivations de canal; à définir une fenêtre de recherche (SW-33) dans l'espace de recherche; et à localiser un indice d'estimation de temporisation de symboles dans l'espace de recherche correspondant à une valeur maximum de l'énergie de la pluralité d'amplitudes estimées de dérivation de canal dans la fenêtre de recherche (1660). Un programme informatique ayant un code et un appareil de communication sans fil pour mettre en AEuvre le procédé sont décrits par les présentes.
