| Abstract: | For the question of carrier acquisition and tracking of high- dynamic spread spectrum signals, the analysis is presented for the influence of Doppler frequency shifts to the design of PLL(Phase-Locked-Loops), FLL (Frequency-Locked-Loops), and loop filters.Also, the question of fast carrier acquisition for high-dynamic spread spectrum signals is analyzed.The new design method of digital complex soft loops is proposed, and the simulation results show that the question of fast carrier acquisition and tracking is solved by this digital complex soft loops. |
