Abstract

In this paper, we propose an unambiguous binary offset carrier (BOC) correlation function with narrow main-peak width for BOC code tracking. Specifically, we first separate a subcarrier pulse into two rectangular pulses, obtain the associated partial correlations, and re-combine the partial correlations to yield the unambiguous correlation function with narrow main-peak width. From numerical results, it is demonstrated that the proposed correlation function provides a significant performance improvement over the conventional correlation functions.

본 논문에서는 binary offset carrier (BOC) 신호 추적을 위해 주변 첨두는 완벽히 제거하면서, 기존의 BOC 상관함수들보다 좁은 폭의 주 첨두를 갖는 새로운 BOC 상관함수를 제안한다. 구체적으로는 BOC 신호를 구성하는 부반송파 펄스를 펄스 구간이 더 좁은 두 개의 펄스의 합으로 해석하고, 그에 따른 부분상관함수들을 생성한다. 이후 부분상관함수들을 재조합함으로써 주변 첨두를 제거하면서도 기존 BOC 상관함수보다 상관함수의 폭이 좁은 새로운 상관함수를 생성한다. 모의실험을 통해 제안한 상관함수를 이용한 경우, 기존의 상관함수들을 이용한 경우들에 비해 더욱 향상된 신호 추적 성능을 가지는 것을 보인다.
