Acquisition of High Dynamic SS Signal with FFT Based in Deep Space Communication

摘要：

In the deep space communication,it has huge difficulty to acquire spread spectrum signals with high Doppler shifts for a receiver. A new receiver architecture is presented, which estimates the Doppler shift during the PN code phase acquisition. This method can search the code phase and estimate the Doppler shifts simultaneously. The simulation and analysis show that the FFT based method can efficiently accelerate the acquisition process.
