Abstract

In the recent years a great deal of attention has been paid to different chaotic synchronization schemes and its applications to encoded communications. The chaotic output of a transmitter system is used as a carrier in which a message is encoded. The amplitude of the message is much smaller than the typical fluctuations of the carrier, so it is very difficult to isolate the message. To decode the message, the transmitted signal is coupled to a similar chaotic system, the receiver, which synchronizes with the carrier itself. The message can be recovered by subtracting the receiver output from the transmitted signal.
