摘要：

To address the problem of time delay signature (TDS) is identified easily in conventional electro-optical delayed feedback chaotic system. This paper proposes a chaotic communication system in the form of an electro-optical cascade, by which two lasers are coupled to each other as driving light sources. It is cascaded with an electro-optical delayed feedback chaotic system to generate a chaotic signal with low TDS. We simulate different system time delays, light source injection intensities and gain constants to evaluate the effectiveness of the system in suppressing TDS.
