Abstract

In this paper, we propose a novel unambiguous correlation function for binary offset carrier (BOC) signal acquisition. Specifically, we first find out that the side-peaks arise due to the fact that the BOC autocorrelation is the sum of the irregularly shaped BOC sub-correlations, and then, propose an unambiguous correlation function with no side-peak by combining the sub-correlations. The proposed scheme is shown to remove the side-peaks completely for any type of BOC signal and to provide a better acquisition performance than the conventional correlation functions.

본 논문에서는 binary offset carrier (BOC) 신호 획득을 위한 새로운 BOC 상관함수를 제안한다. 구체적으로는 BOC 자기상관함수의 주변 첨두가 불규칙적인 모양을 한 부분상관함수의 합으로 인해 나타난다는 사실을 확인하고, 부분상관함수를 새롭게 조합함으로써 주변 첨두가 없는 새로운 상관함수를 생성한다. 제안한 방법은 어떠한 종류의 BOC 신호에 대해서도 주변 첨두가 없는 상관함수를 생성할 수 있으며, 모의실험을 통해 제안한 생성함수를 이용한 경우 기존의 상관함수들을 이용한 경우에 비해 더 좋은 신호 획득 성능을 제공한다는 것을 보인다.
