A rapid Pseudo-Noise (PN) acquisition scheme is proposed. The proposed scheme consists of a phase alignment detector and Voltage Controlled Clock (VCC) loop. The VCC loop is used to control the phase update of the local PN signal. It has an auxiliary signal that provides the loop with two stable locking points as well as the direction of each phase update. The performance of the proposed scheme is evaluated by simulation. Results show that the proposed scheme acquires the phase two to three times faster than the conventional coherent serial scheme, and 1.5 times faster than of that in [10], at a small amount of additional hardware.
