Blind Estimation of the Symbol Period of a Long-Code DS-SS Signal

Abstract

Direct-Sequence Spread Spectrum (DS-SS) signals are widely used in modern communications. The detection and parameter estimation of DS-SS signals in non- cooperative context have been paid many attentions. Up to now, most of the proposed methods consider only short-code DS-SS signals, and long-code DS-SS signals have hardly any been studied. In this paper, a method for blind estimation of the symbol period of a long-code DS-SS signal is proposed. The proposed method is based on further processing of the autocorrelation estimator. Simulation results are provided to illustrate the approach.
