中文摘要	A general framework of PN code acquisition strategy is introduced, and the impact on total acquisition performance when choosing different strategy in each stage is studied based on that framework. Then several decision and verifying strategies that may be used in each stage are studied and four acquisition strategies are presented. Simulation result shows that acquisition performance can be greatly improved by introducing proper verifying strategy during acquisition, while average acquire time only increases slightly. Finally, the performance of the threshold-free acquisition strategy introduced is close to that of the traditional threshold decision strategy.
