Title: BROADCASTING SIGNAL TRANSMITTING APPARATUS AND METHOD FOR CONTROLLING THE SAME
Abstract:
A broadcasting signal transmitting apparatus that transmits a plurality of signals through a plurality of antennas to increase a data transmission rate. The broadcasting signal transmitting apparatus includes a signal generator configured to generate the plurality of signals each of which includes at least one preamble symbol and data symbols, a frequency allocator configured to allocate a first subcarrier position of a whole frequency to a first preamble symbol included in a first signal among the plurality of signals and to allocate, by shifting a frequency position of the first subcarrier position by a preset interval, a second subcarrier position to a second preamble symbol included in a second signal among the plurality of signals, and a transmitter configured to transmit the plurality of signals through the plurality of antennas. The antennas respectively correspond to subcarrier positions allocated to the plurality of signals.
