With the development of optical fiber communication,it is necessary to study a new generation chaotic secure communication system which satisfies requirements of high speed,high security and long distance transmission.In recent years,chaos and cheap evening dresses chaos synchronization of semiconductor lasers(SLs) has attracted much attention for its potential applications in secure communications,various chaotic synchronization schemes have been proposed.In remote chaotic communication system,the chaotic optical signal is degraded during transmission,the factor results in error rate increase and transmission quality reduction,limits the long-range 12hot cheap prom dresses communication distance. Therefore,it has important significance for improving transmission distance and security performance by further increasing optical power and synchronization the flat iron shop for us quality.In this paper,based on the chaos synchronism model of optoelectronic feedback semiconductor lasers unidirectionally coupled in an open-loop configuration,the synchronization discount wedding dresses characteristics and the robustness of generalized synchronization with lace wedding dresses intrinsic parameters mismatch have been investigated.The results show women's nike shoes that the transmitter and receiver lasers have same outputs in complete synchronization system; for generalized discount wedding dresses synchronization,the chaotic dynamics of the receiver laser is functionally related to that of the driving signal,meanwhile the generalized synchronization has good cheap wedding gown dresses tolerance to parameters mismatch.Based on above analysis,a chaotic parallel synchronization model of optoelectronic feedback semiconductor lasers is proposed.
