Abstract

One of the most important problems to be solved in a DS-SS system is the acquisition of the PN sequence. In time-varying environments this fact becomes even more important because the data decoding depends on the performance of the acquisition and tracking. In this work a new sequential acquisition system based on a fuzzy logic controller is proposed. The fuzzy logic controller extracts rellevant information about the transmission conditions improving the the stability and robustness of the receiver.
