中文摘要	GPS软件接收机在移植性、灵活性等方面具有很大的优势。本文从GPS软件接收机的角度讨论了GPS频域相关捕获算法。本文分析了算法的理论模型,并利用Matlab对算法进行仿真实现,成功地解算出GPS信号的码相位偏移和载波多普勒偏移。与传统的滑动相关算法进行了运算量的比较,证明了频域相关捕获算法的优越性。; GPS software receiver had great advantages in reconfiguration and flexibility. In this paper, we discussed the frequency do- main correlation acquisition algorithm in GPS software receiver. Based on the analysis of the acquisition algorithm theoretic model,an acquisition scheme is implemented in Matlab, in which the code phase and Doppler shift in GPS signal can be successfully calculat- ed. Comparison between frequency domain and time domain acquisition method is discussed and the result demonstrated that the for- mer is better than the latter in computation burden.
