Design and Realization of Fast Code Acquisition for Long PN Code Spread Spectrum Communication in LEO Satellite
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 frequency and long PN code spread spectrum communication system is designed and realized in 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 LEO satellite communication.
