The Binary Offset Carrier (BOC) modulated signals have been introduced in global navigation satellite systems (GNSS). They possess good frequency compatibility with existing Binary Phase Shift Keying (BPSK) signal. However, this type of modulation creates multiple side peaks in auto correlation function. Therefore it is hard to make full use of its ranging capability. To alleviate this problem, this...
The Binary Offset Carrier (BOC) modulation is expected to be utilized in the modern Global Navigation Satellite Systems (GNSS) to increase utilization efficiency of the limited frequency spectrum resource. It splits the main energy component of pseudo random noise (PRN) signal spectrum symmetrically around the center, and thus helps to mitigate inter-satellite cross correlation and makes the signals...
The new Binary Offset Carrier (BOC) modulated signals, where the pseudo random noise (PRN) code is multiplied with rectangular subcarriers, split the spectrum symmetrically and reduce interference with existing navigation signals. In spite of these benefits of the Autocorrelation Function (ACF) for BOC signals, e.g. better multipath mitigation and sharper correlation main peak for better tracking...
The new Binary Offset Carrier (BOC) modulated signal obtains good frequency compatibility with traditional Binary Phase Shift Keying (BPSK) signal. However, it raises new challenge for receiver design, i.e. a qualified BOC signal tracking method to alleviate the tracking ambiguity. The two-dimension correlation is utilized in Double Estimator Technique (DET) and performs very well. In this paper,...
