<p>A method for transmitting broadcast signals, the method comprising, encoding Physical Layer Pipe, PLP data for forward Error correction, Multi-input Single-Output MISO, processing the encoded PLP data, Multi-input Multi-Output, MIMO, processing the encoded PLP data, wherein the MIMO processing includes a power imbalance processing by using a power imbalance matrix to contorl a power imbalance of the MIMO processed PLP data, building at least two signal frames by mapping the MISO processed PLP data and the MIMO processed PLP data and modulating data in the at least two signal frames by an Orthogonal Frequency Division Multiplexing, OFDM, method and transmitting at least two broadcast signals having the modulated data by at least two transmission antennas, wherein the modulating includes inserting pilots in the at least two signal frames and wherein amplitudes of the pilots are power imbalance processed by using the power imbalance matrix.</p> |
