Abstract

In this paper we propose a new system for achieving synchronization in asynchronous multi-user chaos-based DS-CDMA. The synchronization is made through a binary code used as a pilot signal and the chaotic signal used as spreading data sequence. The study of this process is evaluated under the assumption of an additive white Gaussian noise channel. The probability of detection and probability of false alarm of this new method are derived.
