N2 - One of the most important problems to be solved in Direct Sequence Spread Spectrum systems is to achieve a robust acquisition of the pseudonoise sequence. In time-varying environments this fact becomes even more important because acquisition and tracking performance can heavily degrade communication reliability. In this work a new multiresolutive acquisition system with a fuzzy logic estimator is proposed. The fuzzy logic estimation improves the accuracy of the acquisition stage compared to the results for the stability controller, through the estimation of the probability of being acquired, and the signal to noise ratio in the channel.
