Classification: CPC H | IPC H

Claim 6:
7. An apparatus for receiving a broadcast signal, the apparatus comprising:
a receiver for receiving the broadcast signal;
a frequency de-interleaver for frequency de-interleaving the broadcast signal including frequency interleaved data by using an interleaving sequence,
wherein the interleaving sequence is generated based on a main interleaving sequence, a symbol offset and an address checker,
wherein the main interleaving sequence is generated based on a FFT(Fast Fourier Transform) size,
wherein when the symbol offset is generated, two consecutive OFDM(Orthogonal Frequency Division Multiplexing) symbols have a value of the symbol offset,
wherein the address checker checks addresses of a first sequence which is generated based on the generated main interleaving sequence and the generated symbol offset and
using the first sequence as the interleaving sequence when the addresses of the first sequence are within a range of an OFDM symbol.
