To solve the problem of channel with distortions, an adaptive circuit is configured by a new laddered method based on relevant articles, and simulation study was made on four dimensional Chua's chaos oscillator. The simulation results demonstrated that: synchronization of two chaotic oscillators can be achieved when adaptive circuit has adaptive capability. Synchronization of two chaotic oscillators cannot be achieved when adaptive circuit has no adaptive capability. Simulation studies were done for five scroll chaotic oscillators that achieve bond-orbit, coupling and pulse synchronization.
