Abstract
Lorenz model and chaos masking /addition technique
Highlights
Berkeley Madonna and Origin Lab software are used to graph and analyze the time series that generated in chaos regime
Experimental results In secure communication, the massage that generated in an arbitrary waveform is modulated with chaotic signal that generated in transmitter Lorenz circuit (Tr) as shown in Fig.5, the carried massage drive to electrooptical converter (E/O), where the carried massage convert from electrical massage to optical massage and drive it to semiconductor laser source
The message could be recover by detected optical-chaos signal (O/E) converter and the synchronization must be happened by the received signal and the local chaos generated signal at the receiving part Fig.5 The synchronization has been made by changing the coupling strength gradually Fig
Summary
Berkeley Madonna and Origin Lab software are used to graph and analyze the time series that generated in chaos regime. Key words Chaotic signals, synchronization, master and slave, Lorenz circuits, optical fiber.
