[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0049] The present invention proposes an offset carrier modulation method (GeneralizedTime Domain Raised Cosine-Binary Offset Carrier, GTDRC-BOC(n,m,ρ)) based on time-domain raised cosine pulse generalization, which not only provides navigation signal design It provides more choices, and can effectively reduce the large side lobe of the power spectrum, reduce the interference to adjacent signals, and improve the power efficiency of navigation signals. At the same time, it has better code tracking performance, anti-multipath and anti- The jamming capability provides a new option for the signal waveform design of our country's future Compass satellite navigation system.
[0050] The object of the present invention is to propose a kind of offset carrier modulation method based on time-domain raised cosine pulse generalization, and its realization process is as f...
