Abstract
A method is presented for receiving broadcast signals. The broadcast signals are received. The received broadcast signals are demodulated by an Orthogonal Frequency Division Multiplex (OFDM) scheme. A signal frame is parsed from the demodulated broadcast signals. Data in the parsed signal frame is bit interleaved. 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 16 Quadrature Amplitude Modulation (QAM), the number of bit groups is 4. The block deinterleaved data is group-wise deinterleaved by a unit of the bit group and parity deinterleaving parity bits of data in the group-wise deinterleaved data. The bit deinterleaved data is decoded.
