SPREAD SPECTRUM COMMUNICATION THROUGH MODULATION OF CHAOS
K. S. HALLE, Chai Wah Wu, Makoto Itoh, Leon Ong Chua · International Journal of Bifurcation and Chaos · 1993
In this letter we demonstrate experimentally how Chua’s circuits can be used to implement a secure communication system. This system is compared to another system proposed earlier. This system has the advantage of transmitting a spread spectrum signal and is also more secure in the sense that better parameter matching is required in order to recover the signal. Furthermore, there is less of a problem with loss of synchronization.
