In order to eliminate the impact of interference signals on our own communication during the implementation of communication jamming,the problem of interference signal cancellation was studied.Considering the quasi randomness of chaos which make it possible for chaotic signals to re-place Gaussian noise as communication interference sources and achieve better interference effects,time-delay SMIB chaotic system was taken as the interference source.Some criteria for achieving glo-bal robust synchronization of two SMIB systems with parameter mismatch and external disturbance via linear state error feedback control were derived,the synchronization error bound was also esti-mated,and the effectiveness was illustrated by the numerical examples.By utilizing this conclusion,it is possible to cancel chaotic interference signals at the communication receiving end,and effectively e-liminate the impact of chaotic interference on oneself.
