FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication engineering and can be used in a digital broadcasting system. In a Digital Video Broadcasting-Cable (DVB-C) system, a transmitter determines the position of broadcast data and the position of reserved tones in a frame and sends a broadcast signal into which the broadcast data and the reserved tones are inserted. A receiver determines the position of reserved tones in a received broadcast signal and extracts broadcast data from the broadcast signal taking into consideration the determined position of the reserved tones. The present system and method may compensate for the peak power of broadcast data to be transmitted through a multichannel bundle, by inserting reserved tones into the whole multichannel bundle with combined channel bands, which reduces the Peak to Average Power Ratio (PAPR) of broadcast signals in the DVB-C system.
EFFECT: high transmission throughput.
