FIELD: radio engineering, communication.
SUBSTANCE: device for transmitting broadcast signals is presented, it comprises the following: an encoder for encoding data on the services, a mapping unit for converting the coded data on the services to a plurality of OFDM-symbols to compose at least one signal frame, a modulator for modulating data in the composed, at least, one signal frame by OFDM scheme (orthogonal frequency division multiplexing), and a transmitter for transmitting broadcast signals having modulated data.
EFFECT: increased efficiency of transmittion of large data volumes, stability of transmit-receive networks and flexibility of the network considering the receiving mobile device.
