FIELD: information technologies.
SUBSTANCE: in one aspect transmitting station generates multiple sequences of pilot signals for multiple transmitting antennas, besides each sequence contains pilot symbols sent in temporal dimension on a separate multitude of subcarriers. Transmitting station additionally generates multiple pilot signals of transfer for transmitting antennas on the basis of sequences. In the other aspect transmitting station generates multiple sequences for multiple transmitting antennas on the basis of multiplexing with code division in frequency dimension (FD-CDM) of sequence specified by value specific for a transmitter. Transmitting station also generates multiple pilot signals of transfer for transmitting antennas on the basis of sequences. In one more aspect transmitting station generates multiple pilot signals of transfer for multiple transmitting antennas on the basis of the first scheme of multiplexing and generates multiple transfers of data on the basis of the second multiplexing scheme, which differs from the first scheme of multiplexing.
EFFECT: improved efficiency of data processing.
