FIELD: information technology.
SUBSTANCE: invention includes signal spectrum extending using multiple codes of spectrum extending where multiple codes of spectrum extending have coefficient of spectrum extending, signal multiplexing with extended spectrum by means of multiplexed transmission with code division, multiplexed signal transmission using multiple adjacent frequency resources of one OFDM character of the first antenna set, and the same multiplexed signal transmission using multiple adjacent frequency resources of one OFDM character of the second antenna set.
EFFECT: improved reliability of data transmission.
