코사인 BOC 신호를 위한 비모호 상관함수 기반의 신호 추적 기법

다국어 초록 (Multilingual Abstract)

In this paper, we propose a sharp correlation function-based unambiguous signal tracking scheme for cosine-phased binary offset carrier (BOC) signals. Specifically, we first divide a BOC sub-carrier into multiple rectangular pulses, and then, generate novel local signals by multiplying rectangular pulses and weight values. Subsequently, we obtain sub-correlations by correlating each of the novel local signals with the received BOC signal. Finally, we generate an unambiguous correlation function with a sharp main-peak by combining the sub-correlations. From numerical results, it is confirmed that the proposed correlation function provides a better tracking error standard deviation (TESD) performance than those of the conventional correlation functions including the BOC autocorrelation function. This is because the proposed correlation function has no side-peaks, and has a sharper main-peak than those of the conventional correlation functions.
