METHOD FOR INFORMATION TRANSMISSION AND DEVICE WHICH IMPLEMENTS SAID METHOD Russian patent published in 1997 - IPC

FIELD: radio engineering. SUBSTANCE: method involves generation of signal which has n-dimensional image of message in its spectrum of (n+1) order, transmission of this signal with multiple spectrum structure through communication line and reading message during receiving using multiple-spectrum analysis of received signal. When n is equal to 2, device has transmission unit which has source of two- dimensional double-spectrum image of message, double-spectrum synthesizer, which has synthesizer for signal with double-spectrum structure in frequency band and double-spectrum converter from frequency to time. In addition transmission part of device has demodulator and transmission line. Receiver has demodulator, double-spectrum analysis unit, which has time-to-frequency converter and correlation meter of third order. In addition device has unit for displaying two-dimensional message. EFFECT: increased stability to wide-band natural and narrow-band industrial noise. 2 cl, 7 dwg
