    摘要： A data transmitter and receiver for improving a data rate, and more particularly, to an apparatus and method of transmitting and receiving an orthogonal frequency division multiplexing (OFDM) symbol in which a pilot signal is added to a data signal is provided. The apparatus includes a transmitter including: a pilot adder to add a pilot signal to a data signal; and a guard interval inserting unit to insert a guard interval to the data signal with the added pilot signal, and a receiver including: a guard interval removal unit to remove a guard interval in a received time domain signal; a fast Fourier transform (FFT) unit to transform the time domain signal in which the guard interval is removed to a frequency domain signal; a channel estimator to estimate a channel value from the time domain signal in which the guard interval is removed; an equalizer to equalize the frequency domain signal based on the estimated channel value; and a pilot signal removal unit to remove the pilot signal in the equalized frequency domain signal.
