The Simulation of BOC Signal and the Verification of the Acquisition and Tracking Algorithm

LI Zhen-b

Abstract

With the modernization of GPS satellite navigation system and the deployment of Galileo satellite navigation system,a new signal modulation scheme called BOC(Binary Offset Carrier) modulation has received an extensive study in the academia.In this paper,the time domain and frequency domain properties of the BOC signal,the acquisition and tracking algorithm of the receiver are presented,and the simulation of BOC(1,1) signal and the verification of the algorithms are implemented with Matlab on a PC.The power spectral density of the simulated signal meets the theoretic derivation,and the acquisition and tracking algorithm of the receiver can acquire and track the BOC signal.
