Abstract
A method for receiving broadcast signals, includes receiving the broadcast signals, demodulating the received broadcast signals by an Orthogonal Frequency Division Multiplex (OFDM) scheme, parsing a signal frame from the demodulated broadcast signals, and bit deinterleaving data in the parsed signal frame, wherein the bit deinterleaving includes block deinterleaving the data with each set of a number of bit groups. The number of bit groups is based on modulation type. When the modulation type is Quadrature Phase Shift Keying (QPSK), the number of bit groups is 2. When the modulation type is 16 Quadrature Amplitude Modulation (QAM), the number of bit groups is 4. When the modulation type is 64 Quadrature Amplitude Modulation (QAM), the number of bit groups is 6. When the modulation type is 256 QAM, the number of bit groups is 8. When the modulation type is 1024 QAM, the number of bit groups is 10.
