Abstract: Disclosed are a method for transmitting and receiving data and an apparatus thereof, and more particularly, a method for transmitting and receiving data and an apparatus thereof in an orthogonal frequency division multiplexing (OFDM) system. The method for transmitting data in an OFDM system according to the present invention includes encoding and modulating data to be transmitted, configuring the modulated data by a frame constituted by N (an integer larger than 0) OFDM symbols, and transmitting the configured frame, in which the frame includes a first OFDM symbol including a pilot symbol and a second OFDM symbol including lower-order modulated than the modulated data.
