摘要

本文介绍了一种新的软件方法“平均相关”，在较小的FFT块上进行块级GPS C/ a码的频域捕获和跟踪。该方法保留了在更昂贵的相关器中观察到的信噪比。将该方法应用于民用GPS接收机，将使频域软件处理变得更加可行和普及。

Averaging correlation for C/A code acquisition and tracking in frequency domain

This paper describes a new software method called "averaging correlation" to do block level GPS C/A code acquisition and tracking in frequency domain with smaller FFT blocks. The method retains the signal to noise ratio observed in more expensive correlators. Frequency domain software processing will become more feasible and popular if this method is implemented in civil GPS receivers.
