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.
