<p>Disclosed are a broadcast signal transmitting apparatus, a broadcast signal receiving apparatus, and a method for transceiving a broadcast signal in a broadcast signal transceiving apparatus. A method for transmitting a broadcast signal comprises the following steps: receiving a broadcast signal transmitted via first and second transmitting antennas, while maintaining the bandwidth of a sub-band constant and changing a tuning frequency for each cell unit, wherein the received broadcast signal includes a signal frame; detecting first and second preamble signals inserted into the signal frame; identifying the pilot location inserted into the signal frame on the basis of the FFT size information contained in the detected first preamble signal and the pilot pattern information contained in the detected second preamble signal, estimating a transmitting channel through which said broadcast signal is transmitted, using the pilot signal at the identified pilot location, and performing channel equalization; and correcting errors of the channel-equalized broadcast signal.</p> |
