| 摘 要： | 从解决GPS接收机受干扰的实际需求出发，阐述了基于LMS算法的自适应滤波器基本原理和不同的噪声产生方式，并对GPS接收机仿真信号与噪声进行叠加。最后用基于LMS算法的自适应滤波器对仿真信号进行消噪处理，得到良好的消噪效果，证明了基于LMS算法的自适应滤波器能够应用于GPS接收机滤波系统。

| Abstract: | This paper introduces the interfering of GPS receiver. Then expatiate the algorithm of adaptive filter based on LMS and different noise produce modes. At the last, the noise of GPS receiver was weakened by adaptive filter based on LMS, and has an effective effect. This paper argues the adaptive filter based on LMS can used in GPS receiver to waken noise. |
