摘要
Abstract
A scheme of chaotic secure communication based on the parameter modula tion and the inversion of a chaotic dynamical system is analyzed. According to this scheme,information signal is modulated by a bifurcation parameter of the transmitter,which is in chaotic state.In the receiver,a proportional integral feedback demodulator is used to demodulate the information signal,which only uses the available synchronizing error as well as stateness of receiver. The purpose of this demodulator is proposed to overcome the influence of differentiation oper ation, nonlinear part and singularities in chaotic system. Numerical simulation is proposed to show the effectiveness of this demodulator.关键词
