Research on Signal Acquisition of BDS Receiver

Abstract

With the development of science and technology, the emergence of satellite navigation system has brought about the revolution of the earth. GPS as the representative of the satellite navigation application industry has gradually developed into a global high-tech industry. China BDS navigation and positioning system has also emerged. In this paper, the signal acquisition part of BDS receiver is studied and discussed. The generation of pseudo-random code is simulated on MATLAB, and the signal acquisition is realized, and the Doppler frequency shift is extracted.
