| 摘 要： | GPS接收信号中的噪声干扰一直以来都是研究人员想方设法消除的不利因素,但在某些非线性系统中,噪声的存在却能够提高信号的检测性能,利用Langevin方程构建的非线性随机共振系统对GPS接收信号进行消噪处理,经过对仿真信号的验证,消噪效果明显,将在GPS接收信号消噪领域得到很好的应用。

| Abstract: | The noise of GPS receiver is weaken by scientists all along.But in some nonlinear system,the noise can enhance the detection capability of the receiver signal.This paper weaked the noise of GPS receiver by a nonlinear system based on Langevin equation.It has a visible result by emulation data,and can be used in GPS receiver. |

| Keywords: | stochastic resonance GPS receiver signal weaken noise |
