Transmitter and receiver of signals through polarization antenna and methods for controlling the same
Disclosed is a data transmitter, including: a demultiplexer configured to demultiplex a data subcarrier, and a training sequence or a pilot subcarrier included in a signal which needs to be frequency-shifted among a plurality of signals; a frequency shift unit configured to frequency-shift the demultiplexed data subcarrier based on a predetermined frequency; a superposition unit configured to generate a polarization signal by superimposing the demultiplexed training sequence or pilot subcarrier, and the frequency-shifted data subcarrier; and a polarization antenna configured to transmit a signal which need not be frequency-shifted and the generated polarization signal among the plurality of signals.
