초록

본 논문에서는 시간 복합 이진 옵셋 반송파 (time-multiplexed binary offset carrier: TMBOC) 신호 추적을 위한 비모호 상관함수를 제안한다. 구체적으로 TMBOC 변조는 두 개의 sine 위상 BOC 신호를 시간 영역에서 번갈아가며 전송한다는 것에 주목하여 각 sine 위상 BOC 신호 별로 신호를 쪼개어 부분 상관함수들을 만들고, 이들을 재결합함으로써 주변 첨두가 없는 상관함수를 생성한다. 모의실험을 통해 제안한 비모호 상관함수를 이용한 경우, 자기상관함수를 이용하는 경우에 비해 향상된 추적 오류 표준편차 성능을 가짐을 확인하였다.

In this paper, we propose an unambiguous correlation function for time-multiplexed binary offset carrier (TMBOC) signal tracking. Specifically, considering that the TMBOC modulation transmits two kinds of sine-phased BOC signals in time domain alternatively, we generate sub-correlation functions for each of the BOC signals by using split sine-phased BOC signals, and then, obtain a correlation function with no side-peak by recombining the sub-correlation functions. From numerical results, we confirm that the proposed correlation function offers an improved tracking error standard deviation performance than the TMBOC autocorrelation function.
