摘要：PN code acquisition is the key to synchronization in direct-sequence spread- spectrum(DSSS) systems. Aiming at the problems in the process of PN code acquisition, the block diagram of acquisition strategy is illustrated firstly. Then, with the choice of different search mode, determination mode and verification mode in the block diagram, the detection probabilities and false alarm probabilities are presented separately, and the false alarm probability of threshold detection method, the detection probability and false alarm probability of maximum-selection determination method are deduced, and all kinds of acquisition strategies are given. Finally, Simulation results shows that the detection probabilities and false alarm probabilities in theory and experiment is consistent with different acquisition strategy, and so does the validation of detection probabilities by maximum-selection method in multiple dwell times.
