Information transfer via implicit encoding with delay time modulation in a time-delay system

A new encoding scheme for information transfer with modulated delay time in a time-delay system is proposed. In the scheme, the message is implicitly encoded into the modulated delay time. The information transfer rate as a function of encoding redundancy in various noise scales is presented and it is analyzed that the implicit encoding scheme (IES) has stronger resistance against channel noise than the explicit encoding scheme (EES). In addition, its advantages in terms of secure communication and feasible applications are discussed.

► We propose new encoding scheme with delay time modulation.
► The message is implicitly encoded with modulated delay time.
► The proposed scheme shows stronger resistance against channel noise.
