An improved method for eliminating deputy peak of BOC navigation signal

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