Synchronization with message embedded for generalized lorenz chaotic circuits and its error analysis

The main concern in this brief is how to design a better receiver structure and its synchronization error analysis, By exploiting a skew-symmetric typ e property existing in generalized Lorenz chaotic systems, me propose a nov el receiver design for synchronizing the transmitter-receiver pair. Error a nalysis carried out by the Lyapunov direct method explicitly shows the rela tion among the magnitudes of the synchronization error, coupling noise, tra nsmitter parameters, and signals. If no noise or message exists in the coup ling channel, then exponential synchronization can be achieved for all stat e signals. As a guideline from the error analysis, a more suitable receiver can be successfully designed and implemented. Experiments are carried out on the circuit of the transmitter-receiver pair to show the performance of the synchronization and secure communication.
