Transmission and Eavesdropping Characteristic in Chaos Phase Modulation
Ryota Nakahama, Hideichi Sasaoka, Hisato Iwai (Doshisha Univ.) RCS2014-357
Abstract (in Japanese) (See Japanese page) 
(in English) Physical layer security techniques have been attracting attention, there is a chaotic communications in one of their implementation means. In this paper, we show that the chaos phase modulation can be improved in characteristics .It is a constant power by phase modulation using chaotic signals. We propose demodulation model and phase estimation model with the maximum likelihood estimation, and evaluate the characteristics of eavesdropping system by using them. It is shown that resistance to eavesdropping system with a maximum likelihood estimation is improved by increasing step times of chaos signal, because chaos has sensitivity to initial conditions.
