Novel experimental synchronization technique for embedded chaotic communications

In this paper, we propose an interesting and original solution to the problem of chaotic synchronization which is focused in its high sensitivity to channel noise. We demonstrate through experimental design, the synchronization of tow embedded hyperchaotic Lorenz generators implemented separately in two FPGA circuits. The basic idea of the proposed solution consists of synchronizing two hyperchaotic systems without perturbing the hyperchaotic dynamic of the slave system. This means that, in an eventual wireless hyperchaotic communication system, whatever the perturbations suffered by the transmitted hyperchaotic carrier (drive signal) through the channel, our solution permits to generate an identical copy of the hyperchaotic carrier at the receiver and then recover the information signal correctly.
