<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, via a first receiving antenna, a first broadcast signal transmitted via first and second transmitting antennas, and receiving, via a second receiving antenna, a second broadcast signal transmitted via the first and second transmitting antennas; detecting first and second preamble signals from the signal frame of the received first broadcast signal to identify the pilot location in the signal frame, estimating a transmitting channel for the first broadcast signal using the pilot signal at the identified pilot location, and performing channel equalization; detecting first and second preamble signals from the signal frame of the received second broadcast signal to identify the pilot location in the signal frame, estimating a transmitting channel for the second broadcast signal using the pilot signal at the identified pilot location, and performing channel equalization; and performing MIMO decoding on the channel-equalized first and second broadcast signals.</p> |
