Abstract：Based on the discrete-time signal processing, the representation of Doppler effect on code acquisition performance is analyzed and the principle of combining partial-matched filter with FFT is given in this paper. A fast code acquisition architecture by using partial-matched filter with FFT for the large Doppler offset and long PN code spread spectrum system is designed and realized with FPGA and DSP. This architecture provides a very good trade-off between acquisition performance and complexity. Application results show this architecture is very attractive for mobile satellite communication and DS/SS anti-jamming communication.
