Multi-User Detection for an Asynchronous Differential Chaos-Based Multiple Access System

Résumé

This paper deals with the bit detection for an asynchronous transmission using a chaos-based multiple access system. Two kinds of detectors are studied: those based on a LMMSE approach, including an adaptive detector, and those based on the estimation of the users' chaotic sequences. Theoretical and simulated performance results are provided, which show the superiority of the first detectors, even when few a priori information concerning the channels is available.
