A Novel Algorithm for the Weak GPS Signals Acquisition

摘要：

　　The acquisition of weak GPS signals is a challenging problem.The current methods for acquisition of weak GPS signals mainly depend on aiding,in which the GPS receiver needs priori information from base-station to promote weak GPS signal acquisition and tracking.It is unavailable in some remote locations since the area may not be covered by the base-station.On the other hand,in the state-of-art unaided GPS receivers,the weak GPS signals acquisition requires long Pre-detection Integration Time (PIT),such that the computation is complex and time-eonsuming.This paper proposes a computational efficient method to speed up acquisition operations.Finally,we evaluate the efficiency of the method through simulations.
