Rapid acquisition techniques for Direct-Sequence Spread Spectrum Systems using an analog detector
Abstract
A rapid acquisition scheme for Direct-Sequence Spread Spectrum systems (DS/SS) is described, whereby the rate of the 'out-of-sync' decisions is an integer multiple of the code chip rate. The acquisition philosophy is briefly outlined and the overall scheme, employing an ideal (analog) detector, is analyzed with emphasis on the acquisition time statistics. Results show a strong dependence of performance on threshold settings and existing signal-to-noise ratio (SNR).
