A FFT-based parallel acquisition algorithm for direct sequence/spread spectrum radio navigation system is studied to solve long PN code acquisition using serial method. Frequency domain analysis of FFT to acquire signal is applied in this paper and state transfer function is used to derive the expression of average acquisition time. Theoretical analysis shows that FFTbased acquisition algorithm can...
It is difficult to realize spread spectrum signal acquisition in time transfer system for a receiver operating in dynamic situation. For a receiver that realized by all-digital model, a new acquisition mode using fast Fourier transform algorithm is presented, which estimates the Doppler shift during the PN phase acquisition. The algorithm presented in the paper solves the problem of signal acquisition...
