This paper proposes a fast unambiguous acquisition technique for binary-offset-carrier (BOC)-modulated signals. We remove the ambiguities (side peaks) of the BOC autocorrelation function (ACF), exploiting a reduced-complexity (real and symmetric) filter composed of only seven nonzero samples. The proposed scheme is applicable to both generic sine- and cosine-phased BOC signals. Theoretical and simulation results show that the proposed method removes the ambiguities in the acquisition problem without requiring an auxiliary signal in the receiver.

Abstract
This paper proposes a fast unambiguous acquisition technique for binary-offset-carrier (BOC)-modulated signals. We remove the ambiguities (side peaks) of the BOC autocorrelation function (ACF), exploiting a reduced-complexity (real and symmetric) filter composed of only seven nonzero samples. The proposed scheme is applicable to both generic sine- and cosine-phased BOC signals. Theoretical and simulation results show that the proposed method removes the ambiguities in the acquisition problem without requiring an auxiliary signal in the receiver.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
