Abstract :
The paper presents a fast non-data aided parallel PN code acquisition method based on FFT. This method improves frequency scan performance and can eliminate influence of data modulation on code acquisition. The proposed method can reduce acquisition time and decrease acquisition threshold. Implementation block diagram of this method is presented in this paper. Theory analysis and simulation results show fast PN code acquisition can be realized under low SNR and high dynamic conditions
