Classification: CPC H | IPC H

Claim 4:
5. A device for receiving a broadcast signal, the device comprising:
a memory; and
a processor coupled to the memory, the processor configured to:
generated a sequence based on a FFT(Fast Fourier Transform)size;
generate a symbol offset, wherein a value of the symbol offset is generated for two consecutive OFDM (Orthogonal Frequency Division Multiplexing) symbols in the broadcast signal; and
check whether values generated based on the sequence and the symbol offset are within a range of an OFDM symbol;
frequency deinterleave the OFDM symbol based on the checked values that are within the range of the OFDM symbol; and
decode the frequency deinterleaved OFDM symbol.
