Provided is an orthogonal frequency division multiplexing (OFDM) transmitter comprising: a Qos tag generator which generates a quality of service (QoS) tag restricting QoS information which is necessary for a mobile baseband data transport; an inverse fast Fourier transform (IFFT) block which transforms the generated Qos tag by using a transformation method suitable for the phase and the amplitude required for the carrier and performs a reverse Fourier transform; an upconverter which carries the QoS tag signals processed by IFFT in a frequency for QoS tag transmission; and a transmission antenna which transmits the QoS tag signals carried in the frequency for the QoS tag transmission. In addition, there is an OFDM receiver having a corresponding structure to the OFDM transmitter, and a mobile baseband data transport system comprising the ODFM transmitter and the ODFM receiver. |
