摘要：
To increase the detection probability of long PN code and decrease its acquisition time, a new method of prepositive chip phase synchronization was proposed based on the analysis of traditional acquisition algorithm. The chip phase is synchronized firstly according to the characteristic of three-order correlation before the synchronization of sequence. The results of theoretical analysis and simulation show that this method can effectively increase the detection probability and decrease the acquisition time.
