N2 - We propose a closed-loop noncoherent Pseudo-Noise (PN) acquisition scheme for Direct-Sequence Spread-Spectrum (DS/SS) systems using an auxiliary sequence, previously used for coherent acquisition. The proposed scheme consists of an alignment detection and a VCC loop for updating the local PN signal and the direction of update. Performance of the proposed scheme are obtained by simulation and compared with a noncoherent fixed-dwell serial scheme. Results show that the proposed scheme acquires approximately three to four times faster than the conventional noncoherent serial scheme.
