Abstract
A transmitting apparatus includes a symbol generator configured to generate a preamble symbol including signaling data and a reference signal, a frequency allocator configured to allocate first subcarriers and second subcarriers to the signaling data and the reference signal, respectively, in a frequency corresponding to the preamble symbol and map the signaling data and the reference signal to the allocated subcarriers, and a transmitter configured to transmit a signal including the preamble symbol and a data symbol, wherein the reference signal is a signal used for channel estimation or frequency offset compensation. Thus, synchronization is accurately corrected and channel estimation is achieved using the reference signal included in the preamble symbol, thereby reducing a ratio of a pilot included in a data symbol.
