摘要

We numerically study a novel scheme of chaotic communication based on delayed optoelectronic feedback semiconductor laser with two time delays. By switching the route of optoelectronic feedback between two time delays according to the message, we can generate a chaotic waveform simultaneously with the message buried inside. With the advantage of generating the chaotic carrier while encoding message, the transmission can be much easier and more secure than conventional chaotic communication systems. The chaotic channel message, decoded message, and filtered message for a message bit-rate of 500 Mbits/s that has a Q-factor value of 9.45 are shown. We also study the Q-factor of the filtered message and the channel message after filtering for different message bit-rates. The result shows that this novel scheme can achieve communication with high bit rate and pertain desirable security.
