Claim Text:
1. An apparatus for transmitting a broadcast signal, comprising: an input formatting module configured to input-format input data into at least one DP(Data Pipe); a BICM(Bit Interleaved Coded Modulation) module configured to perform error correction processing on data of the at least one DP; a frame building module configured to generate a signal frame including the data of the DP; a pilot inserting module configured to insert pilots into the signal frame; and an IFFT(Inverse Fast Fourier Transform) module configured to perform OFDM(Orthoganal Frequency Division Multiplexing) modulation on the signal frame, wherein the pilots comprise CPs(Continual Pilots), SPs(Scattered Pilots) and edge pilots and wherein a first CP set for 32K FFT mode is configured by adding a second CP set to a third CP set and the second CP set is obtained by subtracting carrier indices of the third CP set from a reference value.
