Research Abstract |
This research has been aimed to construct basic theories to develop an efficient secure multiplex communication system based on chaotic pulse-train generators. The major results are as the following : *We have synthesized a circuits that generates various chaotic pulse-train, and have clarified the circuit dynamics theoretically. *We have clarified that chaotic pulse-train can be changed into various stable periodic pulse-trains by discretizing state due to application of higher frequency periodic inputs. We then have constructed a basic theory to use the periodic pulse-trains as rich coding sources. *We have developed a demultiplex system of the stabilized periodic pulse-trains, and have constructed a basic theory to develop the system into higher functional secure multiplex communication systems. *Some circuits have been implemented for chaos generation, pulse-train stabilization, and pulse-train demultiplexing. These circuits designs are suitable for realization on chips. Some of the theoretical results were verified in the laboratory.
