Simulation of chaotic synchronization communication system based on incoherent optical feedback and injection

Abstract:

In this paper,we numerically study chaotic synchronization communication system based on incoherent optical feedback and incoherent optical injection. The characteristics of the system, such as synchronization time,synchronization error, chaos shift keying encoding/decoding and modulation rate are analyzed. The results of simulation show that the system has good synchronization quality and good abilities of robust secure. The synchronization time is 1ns and the chaos shift keying encoding can reach a high rate of 1 Gbit/ s. The system has a good ability of robust secure. It proves the feasibility of the optical secure communication.
