FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication engineering and can be used in multi-carrier systems. The transmission device comprises a frame former, each frame comprising at least two signalling patterns in a frequency direction and one or more data patterns following the at least two signalling patterns in a time direction, wherein each of the data patterns is accompanied by an additional data pattern in the time direction, all data patterns following in the time direction have the same frequency direction structure, each of the at least two signalling patterns and the one or more data patterns comprise a plurality of carrier frequencies, that arranges first signalling data in each of said at least two signalling patterns in a frame, and that arranges data in said one or more data patterns in a frame, whereby the data of said one or more data patterns are arranged in data frames, each data frame comprising second signalling data and content data; a transformer that transforms said at least two signalling patterns and said one or more data patterns from the frequency domain into the time domain to generate a time domain transmission signal.
EFFECT: flexible tuning to any required portion of the transmission band and low overhead.
