초록

Binary offset carrier는 (BOC) 위성 통신 및 위성 항법 시스템 시스템에서 사용될 새로운 변조 방식으로 크게 주목 받고 있다. 본 논문에서는 sine 위상 BOC 신호를 위한 새로운 상관함수를 제안한다. 구체적으로는 BOC 신호 내의 하나의 부반송파 펄스를 다수의 구형 펄스의 합으로 해석하고, 그에 따른 다수의 부분상관함수들을 생성한다. 이후 생성한 부분상관함수들을 새롭게 결합함으로써 주변 첨두가 없는 새로운 상관함수를 생성한다. 모의실험을 통해 제안한 상관함수를 이용하는 경우, 기존의 상관함수들을 이용하는 경우들에 비해 더욱 향상된 코드 추적 성능을 가지는 것을 보인다.

The binary offset carrier (BOC) modulation has attracted much attention as a new physical layer implementation for satellite communication and global navigation satellite systems. In this paper, we propose a new correlation function for sine-phased BOC signals. Specifically, we separate a sub-carrier pulse into several rectangular pulses, and then, generate a number of partial correlation functions. Finally we combine the partial correlation functions to yield an unambiguous correlation function with no side-peak. From numerical results, it is demonstrated that the proposed correlation function provides a significant tracking performance improvement over the conventional correlation functions.
