FIELD: radio engineering, communication.
SUBSTANCE: broadcasting signal is transmitted, which contains data for a service and preamble data, at the same time preamble data bits are represented into preamble data symbols, and data bits into data symbols, at least one data slice is developed on the basis of data symbols, a signal frame is created on the basis of preamble data symbols and the data slice, a signal frame is modulated with the help of a multiplexing method with orthogonal frequency division (OFDM), and the modulated signal frame is sent, besides, data symbols of the preamble are divided into at least one unit of the level 1 (L1), besides, the pass band of the unit L1 corresponds to the number of active subcarriers assigned for one channel, and units L1 are repeated in a frequency area along the pass band.
EFFECT: improved efficiency of data transfer and optimised general reliability of a system.
