| 摘 要： | 文中针对传统串行匹配滤波器在捕获较长伪码时需要消耗大量的硬件资源这一缺陷，对其提出了一种改进方法，并进行了仿真。仿真结果表明该方法在保证平均捕获时间的前提下，极大地降低了对系统资源的占用，同时还有效地减小了接收机的虚警概率，提高了捕获性能。

| Abstract: | The traditional serial DMF would lead to great resource occupation in long PN code acquisition. In this paper, an improved method is proposed, and a simulation model is built to realize this method. Simulation results show that this method could fairly decrease the resource occupation in the average acquisition time, At the same time, the false alarm probability is effectively lowered, and the acquisition capability raised. |
