Claim 0:
1. A device for receiving a broadcast signal, the device comprising:
a receiver configured to receive the broadcast signal;
a frequency de-interleaver configured to:
generate 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; and
check whether values generated based on the sequence and the symbol offset are within a range for an OFDM symbol; and
frequency deinterleave the OFDM symbol in the broadcast signal based on one or more values being within the range for the OFDM symbol;
a decoder configured to decode the frequency deinterleaved OFDM symbol.
