基于采样率变换和循环卷积的GPS信号快速捕获。提出了一种适用于GPS软件接收机的C/A码和多普勒频移的快速捕获算法。该算法结合了采样变换FFT和时域卷积两种方法，提高了捕获速度和多普勒频移的精度。-Based on the sampling rate conversion and fast circular convolution of the GPS signal capture. Presents a GPS receiver software for C/A code and Dopple

该源码通过产生的捕获数据采用FFT及反变换的方法实现信号的捕获。-The source through captured data generated using the FFT and inverse transform method to capture signal.

自己编写的GNSS信号捕获、跟踪算法，使用了fftw库进行傅里叶变换(I have written GNSS signal capture and tracking algorithm, using the fftw library for Fourier transform)
