Abstract: | In this paper, a new four-dimensional autonomous hyperchaotic system
is designed for generating complex chaotic signals. In the design,
its parameters are selected according to the requirements for chaos
and hyperchaos. The hyperchaotic nature is verified theoretically by
using the bifurcation analysis and demonstrated experimentally by
the implementation of an analogue electronic circuit. Moreover, the
Field Programmable Gate Array (FPGA) technology is applied to
implementing a continuous system in a digital form by using a chip
of Altera Cyclone II EP2C35F484C8. The digital sequence generated
from the FPGA device is observed in our experimental setup. |
