Abstract

This paper evaluates the experimental performance comparison between analogue and digital correlation techniques in optical spread spectrum systems. The digital correlation achieved a 3 cm spatial resolution, in comparison with the analogue case of 20 cm. To the authors' best knowledge this is the best resolution reported to date with a non-coherent system. The advantages of the approach are also discussed with reference to synchronization performance.
