VERFAHREN UND GERÄT ZUM ERFASSEN EINES SPREIZSPEKTRUMSIGNALS

An apparatus for acquiring a pseudo-random (PN) sequence timing for a code division multiple access (CDMA) radiotelephone. A buffer stores samples of representations of at least one pilot signal. A correlator coupled to the buffer is operable to correlate at least a portion of the samples with a PN...

description An apparatus for acquiring a pseudo-random (PN) sequence timing for a code division multiple access (CDMA) radiotelephone. A buffer stores samples of representations of at least one pilot signal. A correlator coupled to the buffer 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 coupled to the correlator interrupts the correlator as soon as the PN sequence at a particular PN offset produces a correlation energy at least equal to an energy threshold.
