FIELD: radio engineering, communication.
SUBSTANCE: transmitting object uses different guiding vectors for different subranges to achieve guiding separation. Each guiding vector defines or generates a beam for an appropriate subrange. Any guiding vector may be used for guiding separation. Guiding vectors may be defined so that beams change by subranges in a continuous, and not in a sharp manner. This may be achieved by application of phase shifts that continuously vary by subranges for each transmitting antenna. As an example, phase shifts may vary linearly by subranges for each transmitting antenna, and a different phase inclination may correspond to each antenna. Application of linearly changing phase shifts to modulation symbols in a frequency area may be achieved either by means of a delay or by a cyclic shift of appropriate time counts.
EFFECT: achievement of separation in process of transfer in a communication system based on orthogonal frequency division multiplexing specially for inherited devices with a single antenna.
