De Bruijn sequences as Zero Correlation Zone codes for satellite navigation systems

Abstract

This paper discusses the possible application of an innovative set of binary sequences, the De Bruijn ones, as spreading codes in satellite navigation systems. Binary De Bruijn sequences feature inherent Zero Correlation Zone property, that may be effectively exploited to strongly limit the impact of multi-path and interference. Simulation results are presented, referred to span 5 De Bruijn sequences, to show the orthogonality and correlation-related properties of these codes, that may properly fit the requirements of satellite based navigation systems.
