METHOD FOR DIRECT-CHAOTIC INFORMATION TRANSFER WITH GIVEN SPECTRUM MASK Russian patent published in 2006 - IPC H04B1/04 H04K1/00 

FIELD: information transfer with spectrum expansion, realized by means of chaotic signals.

SUBSTANCE: in accordance to method, at transmitting side information carrier is formed within given frequency range by means of chaotic dynamic system, structure of which is preliminarily synthesized in accordance to given characteristics of information carrier with required spectrum, complete chaotic information carrier is modulated by appropriate information signal and then its transferred along communication channel to receiving side, where receipt and demodulation is performed on received chaotic information carrier by means of dynamic system, synchronized by behavior with chaotic dynamic system of transferring side, while spectral power density of modulated chaotic information carrier satisfies given spectral mask.

EFFECT: information transfer between two or more users with consideration of limits on spectrum density of power of signal transmitted through communication channel.
