The Configuration of a Flexible Control Binary Offset Carrier Modulation Signal

Along with the fast development of spread spectrum communication and global positioning system, varied signal forms are proposed, especially the emergence of BOC modulated signal leads to the characteristics of multi peaks and spectrum splitting. However, consider the need for the flexibility and extensible BOC signals application, a flexible control binary offset carrier modulation signal is proposed in this paper. Based on the BOC modulation signal, the control parameter is defined in the new signal, and the flexible single period subcarrier sequence is generated by configuring the control parameter. Further, the single period subcarrier sequence is periodically expanded to get the subcarrier, which is modulated by PRN code to get FC-BOC signal. This signal has the dynamic and flexibility of the spectrum and correlation function, and can provide a reference for the application of the new generation of spread spectrum signal and navigation signal.
