Digital Transmissions with chaotic signals: Fast receiver synchronization using duplicated chaotic oscillators

Abstract : In recent years, synchronization of chaotic systems and its potential application to secure digital communications have received ever increasing attention.Due to their high sensitivity to initial conditions, chaotic oscillators are difficult to synchronize. Furthermore,synchronization must be performed for each new symbol,so synchronization time puts a strong limitation on possible bit rates (the symbol period cannot be less than the synchronization time). In this paper, we propose an improvement to the structure of a chaotic receiver, in order to reduce the time needed for synchronization. The idea is to duplicate each receiver chaotic oscillator. A free-mode version of each receiver oscillator is used as a short term dynamic memory. At the end of each symbol period,information is transferred between the copies and the initial oscillators.Experimental results show that using this method yields to a significant reduction of synchronization time.
