Abstract

Signal search and acquisition is an important part of GPS software receiver and makes an influence on the working performance of it. This paper discusses a frequency domain parallel acquisition algorithm. Its theoretic model is first analyzed and then implemented in Matlab, in which the carrier frequencies and code phases in GPS signal can be successfully calculated. Comparison between the conventional time domain serial search and proposed frequency domain parallel acquisition method is discussed. It is verified that the proposed method has better performance both in computation and accuracy.
