We characterize a recently proposed new integrated communication scheme fully based on chaos theory (Phys. Rev. E 62 (2000) 4835). We show that this method is very efficient, i.e., it sends large amounts of information with low bit-error rate. This is achieved because we explore the deterministic characteristic of a chaotic system, using it to predict non-transmitted signals. (C) 2003 Elsevier Ltd. All rights reserved.
