Claim 2:
3. A method for receiving a broadcast signal, the method comprising:
receiving the broadcast signal;
frequency de-interleaving the demodulated broadcast signal using a de-interleaving sequence,
the frequency de-interleaving comprising:
generating a sequence based on a FFT(Fast Fourier Transform) size;
generating a symbol offset, wherein a value of the symbol offset is generated for two consecutive OFDM(Orthogonal Frequency Division Multiplexing) symbols; and
checking whether values generated based on the sequence and the symbol offset are within a range of an OFDM symbol and outputting one or more values as the de-interleaving sequence based on the one or more values being within the range of the OFDM symbol; and
decoding the frequency deinterleaved broadcast signal.
