A CDMA receiver includes a plurality of RAKE branches for despreading the received CDMA signals over a corresponding plurality of paths and a single tracking device that is shared among the plurality of the RAKE branches for tracking the delays of the received CDMA signal over a corresponding path. Similarly, a method for tracking a CDMA signal correlates the received signal with local PN code using a plurality of RAKE branches and tracks the received signal using a single tracking device that is shared among the plurality of the RAKE branches.
L'invention porte sur un récepteur CDMA comprenant une pluralité de dérivations RAKE permettant de désétaler les signaux CDMA reçus sur une pluralité de voies correspondantes, et un dispositif de poursuite unique qui est partagé entre la pluralité de dérivations RAKE de façon à suivre les retards des signaux CDMA reçus sur une voie correspondante. De manière similaire, l'invention porte sur un procédé de poursuite d'un signal CDMA qui met en corrélation le signal reçu avec des codes pseudo-aléatoires locaux utilisant une pluralité de dérivations RAKE, et qui suit le signal reçu à l'aide du dispositif de poursuite unique qui est partagé entre la pluralité de dérivations RAKE.
