摘要：
To solve the problem of fast acquisition of long PN code, after analyzing the performance of existing iterative PN code acquisition algorithms, an improved method was proposed which is called multi-iterative PN code acquisition algorithm. The iterative process of the improved method was showed, and the comparative performance of the improved method and the original one was analyzed. Simulation results show that the new algorithm can decrease the bit error rate of MAP, and the optimal algorithm parameter is got.
