Abstract: Methods and apparatus for wireless communications are described. A method of wireless communications includes determining an energy for a first signal received at a first finger of a rake receiver after a reference signal is received at a second finger of the rake receiver, determining an energy for a second signal received at a third finger of a rake receiver before the reference signal is received at the second finger of the rake receiver, and selecting the first signal as a new reference signal when the energy of the first signal exceeds the energy of the second signal by a predefined threshold amount. In another aspect, a method includes assigning a signal received at a rake receiver to a finger of the rake receiver, and deassigning the finger if the signal has an energy level below a preselected lock threshold energy for a predefined time.
