Abstract: | Aiming at improving acquisition performance for direct sequence spread spectrum (DSSS) signals, a new acquisition algorithm based on fast Fourier transform (FFT ) is proposed. The code phases are parallel searched throughout the Doppler freq uency domain. Since the influence of Doppler frequency errors on peak-to-avera ge ratios of correlation power shows a pattern similar to the sinc function, it is our belief that by judging on peak-to-average ratios for different Doppler frequency errors false alarm prob... |
