Abstract
A method and device for processing broadcast signals are discussed. The method includes receiving the broadcast signals carrying service data, demodulating the broadcast signals by an Orthogonal Frequency Division Multiplexing (OFDM) scheme, MIMO processing data in the broadcast signals based on a rotation value, where the rotation value has zero (0) degree for a modulation order corresponding to equal to or greater than 64 Quadrature Amplitude Modulation (QAM) and a code rate corresponding to at least one of 2/15, 3/15, 4/15, 5/15, 6/15, 7/15, 8/15, 9/15, 10/15, 11/15, 12/15 or 13/15, and the rotation value has zero (0) degree for a modulation order corresponding to Quadrature Phase Shift Keying (QPSK) and a code rate corresponding to at least one of 2/15, 3/15, 4/15 or 5/15, and decoding the data.
