Abstract
A method of activating a radiotelephone operable in a spread-spectrum multiple access radiotelephone system. A searcher receiver (114) is activated, and the searcher receiver (114) acquires a PN sequence timing of a pilot signal. At least one demodulation branch (122) is activated after activation of the searcher receiver (114), and the demodulation branch synchronizes to the PN sequence timing of the selected pilot signal after the searcher receiver (114) has acquired the PN sequence timing.
