RADIO COMMUNICATION METHOD Russian patent published in 2005 - IPC

FIELD: radio engineering.

SUBSTANCE: artificial non-homogeneousness is made reflective at N₁ bearing frequencies and through at N₂ frequencies, using aforementioned artificial non-homogeneousness, by means of demodulation and filtering N₁+N₂ primary information signals of N₁+N₂ clients are selected, positioned respectively in both semi-spheres relatively to artificial non-homogeneousness, value of information, carried by these signals, is estimated, close to artificial non-homogeneousness N₁+N₂+N₃+N₄ of bearing signals are additionally generated, modulated by same number of primary information signals, these are then used to effect forming of artificial non-homogeneousness by changing resistance of controlled layer, N₁+N₂ radio communication channels are organized, while N₁ channels are organized by means of reflection of signals to semi-sphere, in which first two clients and N₁ clients are positioned, N₂ channels are organized by letting N₂ signals through artificial non-homogeneousness to another semi-sphere, in which N₂ clients are positioned, using transceivers N₁+N₂ twice modulated signals are received and by demodulation and filtering N₁+N₂ primary information signals are separated from these, N₃ sub-carrying signals, modulated by same number of primary information signals, are used to protect useful information, transmitted via one part of N₁+N₂+2 radio communication channels by encoding in accordance to rule, known at receiving side and unknown to other clients, N₄ sub-carrying signals, modulated by same number of primary information signals, are used to destroy information, sent along other part of N₁+N₂+2 radio communication channels by changing parameters of signal in accordance to rule, unknown at receiving side.

EFFECT: higher efficiency, broader functional capabilities, higher resistance to interference.
