Abstract:

The purpose of this DREO Technical Note is to present experimental and theoretical results on the properties of the cross correlations of maximum length direct sequences m-sequences. The code correlation families and the relationship between full-period and partial-period correlations are described. Results from the software developed to study the cross-correlation properties of the 8-stage m-sequences, denoted R8s, as well as, results obtained from the optical correlator and the theoretical studies are presented. The software developed to analyze the cross-correlation functions was also suitable for the study of partial-period correlation functions and the effects of phase shifts on partial-period correlation functions. Properties of partial-period correlation functions are also analyzed and a generalization to - longer m-sequences is presented. The results from the optical correlator demonstrate that it is possible to visually identify the m-sequences family associated with the cross-correlations for those which have the strongest features.
