COMMUNICATION SYSTEM OF MILLIMETER AND SUB-MILLIMETER WAVE RANGE (VARIANTS) AND RECEIVER-TRANSMITTER FOR COMMUNICATION SYSTEM OF MILLIMETER AND SUB-MILLIMETER WAVE RANGE AND METHOD FOR COMMUNICATION IN SUB-MILLIMETER WAVE RANGE Russian patent published in 2008 - IPC H04B15/00 H04B10/00 H04B10/30 G02F1/15 

FIELD: communications engineering, possible use during realization of relay broadband communications, in local high speed networks, for wireless communications of various life support systems within buildings, for concealed communications.

SUBSTANCE: in accordance to the invention, system, method and device use generation of two carrier oscillation-signals (or more than two carriers), modulation of carriers with information signal by changing their mutual frequency, phase or amplitude difference or a combination thereof, combination of carriers in form of their total in a radio-signal. Demodulation in receiving section includes extracting aforementioned differential signal of pulsations and first carrier from radio signal, used later on for precise adjustment of heterodyne signal.

EFFECT: creation of system and method for communication in millimeter and sub-millimeter ranges with high spectral density of information channels for signals with any - wide or narrow - band of information signals.
