Chaos shift keying with an optoelectronic encryption system using chaos in wavelength

A chaos shift-keying modulation scheme in which the transmitter and the receiver are nonlinear time-delayed feedback systems is described. The change in the chaotic dynamics is discussed when different parameters are used to encode digital signals. The time-delay parameter is shown to assure the bes...

Zusammenfassung:	A chaos shift-keying modulation scheme in which the transmitter and the receiver are nonlinear time-delayed feedback systems is described. The change in the chaotic dynamics is discussed when different parameters are used to encode digital signals. The time-delay parameter is shown to assure the best conditions for data recovery.
