The present invention is a novel and improved method and apparatus for performing position location in wireless communications system. One embodiment of the invention comprises a method for performing position location comprising the steps of receiving signal samples, generating a coarse acquisition sequence, rotating said coarse acquisition sequence yielding a rotated coarse acquisition sequence, and applying said rotated coarse acquisition sequence to said signal samples at a set of time offsets yielding correlated output data.
L'invention concerne un procédé et un appareil nouveaux et améliorés pour la localisation dans un système de télécommunication sans fil. Dans un mode de réalisation, l'invention se rapporte à un procédé de localisation qui consiste à recevoir des échantillons de signaux, à générer une séquence d'acquisition grossière, à faire tourner ladite séquence d'acquisition grossière de sorte qu'une séquence d'acquisition tournée soit produite, et à appliquer ladite séquence d'acquisition grossière tournée auxdits échantillons de signaux, selon un ensemble de décalages temporels, si bien que des données de sortie corrélées sont produites.
