Abstract:
Disclosed herein are a method for transceiving a broadcast signal using a combination of multiple antenna schemes with layered division multiplexing and an apparatus for the method. A method for receiving a broadcast signal includes generating received signals based on signals that are received through multiple receiving antennas, estimating channels between the receiving antennas and transmitting antennas, restoring a core-layer signal corresponding to the received signals, and restoring an enhanced-layer signal based on a cancellation process, wherein the cancellation process corresponds to the core-layer signal and is separately performed for the individual receiving antennas.

Claim (Index 1):
An apparatus for transmitting a broadcast signal, comprising:\n an enhanced layer Bit-Interleaved Coded Modulation (BICM) unit for generating a first enhanced-layer signal and a second enhanced-layer signal by dividing an enhanced-layer data stream into two different enhanced layer sub-streams and by performing Multiple-Input Multiple-Output (MIMO) precoding corresponding to the enhanced layer sub-streams; a first combiner for generating a first multiplexed signal corresponding to a first antenna by combining a first core-layer signal corresponding to a core-layer data stream with the first enhanced-layer signal at different power levels; a second combiner for generating a second multiplexed signal corresponding to a second antenna by combining a second core-layer signal corresponding to the core-layer data stream with the second enhanced-layer signal at different power levels; and Radio Frequency (RF) signal generation units for generating a first RF transmission signal and a second RF transmission signal, wherein the first RF transmission signal corresponds to the first multiplexed signal and is to be transmitted through the first antenna, and the second RF transmission signal corresponds to the second multiplexed signal and is to be transmitted through the second antenna.
