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.

本研究的目的是为基于混沌脉冲序列发生器的高效保密多路通信系统的研制提供理论基础。主要结果如下：* 我们合成了一个产生各种混沌脉冲串的电路，并从理论上阐明了电路的动力学特性。*我们阐明了由于施加较高频率的周期输入，混沌脉冲序列可以通过离散化状态而变成各种稳定的周期脉冲序列。然后，我们建立了一个基本理论，将周期性脉冲序列用作丰富的编码源。我们研制了一种稳定周期脉冲序列的解复用系统，并为将该系统发展为高性能的保密多路通信系统奠定了基础理论。一些电路已经实现了混沌产生，脉冲串稳定，和脉冲串解复用。这些电路设计适合于在芯片上实现。部分理论结果在实验室得到了验证。
