摘      要：As a novel rapid acquisition scheme, the partial correlation with frequency sweeping (PC-FS) method is proposed for acquisition of direct-sequence spread-spectrum (DSSS) signal in the presence of Doppler shift. The output performance of the PC-FS scheme is analyzed and a hardware structure which can largely accelerate the synchronization process is designed. Application results show that new acquisition scheme can provide a significant improvement in flexibility and efficiency over the PMF-FFT method.
