Abstract :
The performance of a noncoherent, serial acquisition technique is evaluated for direct-sequence spread-spectrum packet communications. The output of a filter matched to the packet´s preamble is sampled at twice the chip rate during acquisition, and each sample is compared with a fixed acquisition threshold. The effect of sample-timing error on the acquisition performance is examined.
