Abstract: Optical communication system using a chaos based signal transmission scheme has been proposed to transmit digital information signal by using the conventional synchronization of chaos and digital transmission approaches. In this scheme either a chaotic or hyper chaotic system is used to generate a chaotic signal. This signal along with the information digital signal is used to generate the transmitted signal. The transmitted signal is then masked by one of the chaotic signal of the transmitter and is transmitted through the channel to the receiver as well as used to drive the transmitter chaotic system using the concept of self-modulation. At the receiver end, suitable subtractor circuit is constructed for unmasking and the reception rule is used to recover the information signal. The effect of typical perturbing factors like channel noise and parameter mismatch are also included and their corresponding performance analysis has been done. By considering appropriate circuit configuration, the results of experiment are also presented.
