Abstract

In this paper, we propose a novel cancellation scheme of correlation side-peaks for binary offset carrier (BOC) signals. The proposed scheme is based on a combination of the sub-correlation functions composing the BOC autocorrelation and applicable to both sine- and cosine-phased BOC signals without requiring any auxiliary signal in the receiver. From numerical results, it is confirmed that the proposed scheme provides a better tracking accuracy than the conventional schemes.

본 논문에서는 binary offset carrier (BOC) 신호를 위한 새로운 상관함수 주변첨두 제거 기법을 제안한다. 제안한 기법은 BOC 자기상관함수를 구성하는 부상관함수의 결합에 기반을 두고 있으며, 수신기에서 보조 신호를 필요로 하지 않고, sine 위상 및 cosine 위상 BOC 신호에 모두 적용이 가능하다. 또한 모의실험 결과를 통해 제안한 기법이 기존의 기법들에 비해 더 좋은 신호 추적 성능을 가짐을 보인다.
