Communication by chaotic signals : the inverse system approach

摘要: The inverse of a non-linear dynamical system is introduced and its synchronization with the original discussed. If chaotic if despite this synchronizes, two systems can be used respectively as modulator demodulator for carrier signal. transmitted signal then hidden in chaos. We show that have different order from system. difference corresponds to relative degree In an reduced it easier achieve synchronization; on other hand, such may distort noisy input considerably. Examples literature are discussed point view reduction. New circuit examples given where output not variables at same port, case all published context communication signals. Finally, quite general structure together designed given.
