摘　　要：通过对伪码捕获原理进行分析以及对各种捕获方法进行比较,确定一种性能好、易实现的串并混合搜索捕获方案。并给出了一个在实际系统中成功应用的捕获电路,用Modelsim对伪码捕获电路部分模块的性能进行了仿真。By analyzing the operational principle of PN-Code acquisition and comparing traditional classical methods, a bunching and combining PN-Code acquisition project of good performance and easy implementation is designed. A circuit of PN-Code acquisition which is successfully applied in practice is given. The performance simulation results of the PN-Code acquisition is given by modelsim.
