Abstract:	The binary offset carrier (BOC) modulation is used in several signals in the next generation GNSS. The multiple zero crossings and peaks in its autocorrelation make BOC signals much more difficult to receive than traditional BPSK signals. The technique which can prevent the miss detection and false lock has been a research hotspot in the last decade. One effective and robust category called dual sideband techniques is widely focused on, which includes BPSK-like method and second order BPSK-like for BOC signal acquisition, and dual sideband for BOC signal tracking. All the above techniques are based on the fact that the upper and lower sideband of BOC signals can be approximately considered as BPSK signals, so the dual sideband signals could be received by mature BPSK receiving techniques. However, the principle of dual sideband technique has not been theoretically analyzed. In this paper the dual sideband model of ideal band-limited BOC modulated signals is derived at first, and then the dispersive effect of ionosphere is considered. After that three technique based on the dual sideband model is introduced, and their performance is analyzed.
