METHOD FOR TWO-DIMENSIONAL INTERFERENCE-RESISTANT INFORMATION ENCODING IN SPATIAL PARALLEL RADIO CHANNELS OF ROBOTIC COMPLEXES Russian patent published in 2021 - IPC H03M13/51 H04L27/34 H04B1/713 

FIELD: encoding.

SUBSTANCE: invention relates to the field of interference-resistant encoding and can be used for encoding and transmitting information in the communication systems of robotic complexes. Proposed is a method wherein the states of radio channels are determined, information about the state of radio channels is transmitted to the receiver of the data transmission system of the robotic complex, the radio channels with the best quality states are determined, said channels are declared control channels, and the remaining radio channels are declared basic channels, a time interval equal to the length of the code word is set, the source data is divided into fragments according to the amount of basic radio channels, the lengths of the fragments are ranked based on the data on the state of the radio channel as the remainders from the division on the basic bases of the system in the residual classes, wherein the system of residual classes is set either in an integer algebraic principal ideal ring, or by polynomials of the expanded Galois field, the basic and control bases are determined for each radio channel. A spatial data vector is formed and, based on a pseudo-random sequence, carrier frequencies are formed for each radio channel, carrier frequencies are modulated with the fragments. A spatial-frequency matrix of modulated signals is received and supplied to the inputs of the diagram-forming antenna combination configuration in the form of a multi-beam adaptive antenna array, wherein beams are formed for basic and control radio channels, the parameters of the beams are controlled by an adaptive processor, and the modulated signals are transmitted via the beams to receivers.

EFFECT: increase in the interference resistance of the transmitted data and the bandwidth capacity in spatial parallel radio channels.
