Abstract: The present invention relates to a method for removing a side peak of a BOCsin(n,n) signal, comprising: generating a correlation function of a local BOCsin(n,n) signal and a received BOCsin(n,n) signal in synchronization of the BOCsin(n,n) signal among sine phase binary offset carrier (sine phase BOC) signals; acquiring an absolute value oaf the correlation function; and combining the correlation function with the absolute value of the correlation function. According to the present invention, since only the autocorrelation function is used in combination, an arithmetic operation is simple as compared with the prior art. Since the magnitude of a main peak is not reduced, a signal tracking function is improved and thus reliable code tracking is possible. Also, since the side peak is completely removed, no signals are acquired in the side peak of the BOC autocorrelation function and thus noise is remarkably reduced. In addition, since a single branch correlator is used, a circuit is easily implemented.
