Abstract

Multipath is one of main error sources in code tracking in global navigation satellite system. One of the first approaches to mitigate multipath is called Double Delta Correlator (DDC). This technique originally applied to Global Positioning System signals (C/A signals) which are Binary Phase ShiftKeying ones and have a single–peak autocorrelation function. Latter, it also applied to new GNSS signals which are binary offset carrier (BOC) modulated ones. It shows a good code multipath performance for mid-delayed and long-delayed multipath in both cases. For short-delayed multipath, there is still remaining error. This paper presents an Improved DDC that could reduce the error for short-delayed multipath signals. This improved DDC method is proposed for BOC signals. The simulation results show a better performance of proposed method than conventional DDC.
