The Research of Side-Band Acquisition for BOC-Modulated Signal

Binary Offset Carrier modulation has the special character of splitting spectrum, but usually each band of the spectrum has the information for demodulation, in a sense that each band is redundant to another, so the receiver can process only one of them. Because the correlation function is the most important for the acquisition stage of the receiver, so, as an example, The analytic formula of power spectral density function and autocorrelation function for BOC (8,4) are deduced at first in this paper, then base on them, the FFT algorithms is chosen for the side-band acquisition of the BOC-modulated signal, through the simulation and analytic, the feasibility of this acquisition scheme is validated at last.
