| 摘 要： | 综合时域滑动相关法、差分匹配滤波器算法和基于块处理的频域捕获算法等三种方法各自的优点,提出了一种新的基于差分C/A码和块处理方法的GPS信号时域捕获算法,在不损失处理增益的前提下既加快了捕获速度,又降低了资源消耗,实现了捕获时间和资源占用二者的最佳结合。实验结果表明此算法是行之有效的。

| Abstract: | A novel GPS signal acquisition algorithm using differential C/A codes and block processing techniques was proposed.It was integrated with the advantages of serial correlation method in the time domain,differential digital matched filter method and block processing techniques in the frequency domain,and realized a good compromise be-tween acquisition time and resources consumption,which not only improved the acquisition speed but also reduced the hardware consumption while maintaining an identical processing gain.The experiment results show the algorithm can work well. |
