An improved method for eliminating deputy peak of BOC navigation signal

Abstract

This paper introduces a new acquisition technology, which can completely eliminate side peaks and obtain better acquisition performance. This method is effective for BOC(n,n) modulated signals. The basic idea of this method is to construct a special local auxiliary signal, cross-correlate it with BOC modulated signal, and use the cross-correlation function curve and autocorrelation function curve to do certain operations to eliminate the secondary peaks of autocorrelation function curve. Experimental results show that compared with other typical algorithms, this algorithm can better and thoroughly eliminate the secondary peaks of BOC signal.
