METHOD FOR SPACE-TIME MULTIBEAM CODING OF INFORMATION BASED ON A MULTIBEAM ADAPTIVE ANTENNA ARRAY Russian patent published in 2020 - IPC H03M13/00 H01Q21/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to a method of space-time multibeam coding. Disclosed is a method for space-time multibeam coding of information based on a multibeam antenna array, comprising: introducing a space-time coding scheme which generates a space-time matrix, introducing a multi-beam adaptive antenna array forming diagram, which generates two beams, in a time slot with a duration of one symbol interval, a combination of symbols z₁·z₂* transmitting to the first input of the beamforming circuit of the multibeam adaptive antenna array and transmitting by the first beam of the multibeam adaptive antenna array, combination of symbols z₁*·(-z₂) is fed to the second input of the beamforming circuit of the multibeam adaptive antenna array and transmitted by the second beam of the multibeam antenna array during one time slot, an adaptive processor is added, which is responsible for phasing of the multibeam adaptive antenna array and the shape of the beam.

EFFECT: improved signal quality at the receiving point and shorter symbol transmission time.
