Since the existing side-peaks cancellation (SC) techniques is still scarce of uniform theoretical frame and analytical method

a new SC analytic design general framework is proposed in this paper.In this framework

the existing techniques based on the combination of correlation functions for Binary Offset Carrier (BOC) signals can be unified

and more importantly

it can provide an analytical tool for SC.This framework is implemented to present a generalized spreading symbol waveform

and create the combinations of cross-correlation function between the BOC signal and the local signal in receiver.And it is confirmed with the mathematical theory based on practical methods.Finally

an unambiguous tracking method based on a combined correlation function for BOC signals is also proposed.Theoretical analysis and simulation results indicate that the proposed method can remove the side-peaks of BOC autocorrelation function completely while maintaining the shape of main peak

and it exhibits an average multipath performance.
