Subcarrier synchronization for satellite USB TT&C
Jilin-1 satellites TT&C adopts USB system. The receiver adopts the architecture FFT+DPLL1+DPLL2. FFT mainly realizes coarse capture of carrier. DPLL1 realizes tracking of carrier phase on the basis of FFT. DPLL2 realizes subcarrier tracking. This paper studies the digital PLL technology used in...
