<p>An apparatus (114) for acquiring a pseudo-random (PN) sequence timing for a code division multiple access (CDMA) radiotelephone (104). A buffer (230) stores samples of representations of at least one pilot signal. A correlator (202) coupled to the buffer (230) is operable to correlate at least a portion of the samples with a PN sequence at each of a plurality of different PN offsets to produce corresponding correlation energies. A controller (116) coupled to the correlator (202) interrupts the correlator (202) as soon as the PN sequence at a particular PN offset produces a correlation energy at least equal to an energy threshold.</p> |
