Simulation of BOC Waveform and Study on Accuracy Improvement of Navigation Positioning Satellite System

Wei Li

Abstract

To meet high accuracy and anti-interference requirements of spacecraft and missiles,Galileo and M code of GPS system use Binary Offset Carrier(BOC) modulation.Galileo and M code of GPS signals and their anti-multipath performance have been simulated.The results show that BOC modulation can separate the newly added signal from the existing spectrum and has better anti-interference and anti-multipath performance.
