Digital Communication using Synchronized Hyperchaotic Maps
This paper describes the analysis and practical implementation of
synchronized hyperchaotic maps for private communication of digital data. The
data is transmitted using chaotic masking and demodulated using a matched
filter (integrate and dump) receiver, which is shown to be nearly optimal in
this case. Simulation results were validated by implementing two maps on
circuit boards using high-speed discrete components. Experimental results show
a bit error rate (BER) of 2x10-6 at a bit rate of 10 kbps and a clock frequency
of 0.5 MHz, which is sufficient for high-fidelity real-time speech and image
transmission without additional error control coding.Comment: Paper under review (International Journal of Bifurcation and Chaos
