Research on the quick acquisition of high dynamic spread spectrum signal

The speed of vehicles has been making too many breakthroughs, even 20 times of the speed of sound has been achieved. When using high communicating frequencies, it has huge difficulty to acquire spread spectrum (SS) signals with high Doppler shifts for a receiver. This article studied a time domain parallel acquisition method based on FFT, carrier tracking method for PLL-ring with FLL-ring, getting a full set of signal receiving scheme. Theoretical analysis and simulation results show that the algorithm in this article can complete acquisition.
