一种基于FFT的GPS信号快捕算法

A Rapid Algorithm of GPS Signal Acquisition Based on FFT

摘要:

提出了一种利用1 024点的FFT模块来实现快速捕获GPS卫星信号的具体实现方法；并利用这种快速捕获方法,对真实采集的GPS信号进行捕获,验证了该方法的可行性。在硬件中采用这种方法,可以利用较少的硬件资源来对GPS信号实现快速捕获。

Abstract:

To realize GPS signal rapid acquisition, a method that used 1024 points FFT algorithm was presented in this paper. Real GPS data was acquainted with this method that the feasibility was validated. If the method is implemented in hardware, less hardware source will be utilized to achieve rapid acquisition.
