Abstract:

Sequential PN code acquisition schemes have the potential to achieve the best performance, but they are the least analyzed because of the analytical difficulties. In recent studies, we have proposed and investigated the truncated sequential probability ratio test TSPRT for spread-spectrum noncoherent PN code acquisition. It was shown to be much better than the conventional fixed sample size FSS scheme in the average sample number ASN at fixed detection and false-alarm probabilities. For system design purposes, however, the mean acquisition time is more informative. In this paper, we report results on the mean acquisition time for the TSPRT. Numerical data that includes Rician fading effect is also presented. Our results show that the proposed TSPRT is efficient, robust against fading, fast, and suitable for real-time low-cost implementation.
