摘要：
For the problem 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. A new design scheme of digital complex soft loop is proposed, and the simulation results show that the problem of fast carrier acquisition and tracking can be solved by this digital complex soft loop.
