Communication system via chaotic modulations is demonstrated. It contains the well-known chaotic circuits as its basic elements - Chua's circuits. The proposed system has some standard properties of spread spectrum communication. The following advantage is found in simulations: a) Transmitted signals have broad spectra. b) Secure communications are possible in the sense that the better parameter matching is required in order to recover the signal. c) The circuit structure of the communication system is most simple and communication systems are easily built at a small outlay. Finally computer simulations are given to examine the validity of this system.
