摘　　要：针对GPS接收机在接收信号的过程中经常存在由于干扰信号的影响而导致接收机无法跟踪锁定有用信号,从而失去精确导航定位的能力问题,提出了一种在天线部分增加一个自适应抗干扰模块的解决办法,并用TI公司的TMS320C6416芯片实现了该方案。In this paper, the authors aim at the problem that GPS receivers often lose useful signals because of the effect of various interfering signals in the period of receiving signals. As a sequel of it, GPS receiver will be out of work and can not provide users with its excellent support for accurate navigation and positioning. So the authors put forward a method to resolve this problem by adding an adaptive anti-jamming module to the antenna of GPS receiver, and select TMS320C6416 chip to realize this design.
