Digital Communication using Synchronized Hyperchaotic Maps
英文摘要：
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.
