Chaotic communication with robust hyperbolic transmitter and receiver

New chaos-based communication schemes for transmission of analog and digital information are suggested. The carrier signal is produced by chaotic generator having well-defined oscillation phases at least on short time intervals. For data extraction, a special procedure of phase detection for chaotic signals is developed. An efficiency of the scheme is demonstrated by examples of coupled generators of structurally stable (robust) chaos with hyperbolic attractors of Smale-Williams and Arnold's “cat map” types. Robustness of the transmitter and the receiver makes it possible to transmit information in presence of parameter mismatch or additive noise in the communication channel.
