Embodiment Construction
[0038] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0039] like figure 1 , figure 2 and image 3 As shown, in this embodiment, firstly, according to the performance requirements and constraints of the navigation system, the frequency f of the spreading code is determined c =1.023MHz, subcarrier frequency f cs =1.023MHz, determine the variable parameter ρ=0.2 of modulation waveform, determine to adopt cosine type modulation; Then determine the number K of half-period subcarrier chips in a spread spectrum chip according to the determined spread spectrum code frequency and subcarrier frequency , to construct a cosine-type generalized binary offset carrier GBOC cos (f cs , f c , ρ) modulation, the specific steps are as follows:
[0040] Step 1: First, according to the requirements and constrain...
