Claim:
1. A transmitting apparatus, comprising: an input processor configured to process an input stream to generate at least one frame; a bit interleaved and coded modulation (BICM) processor configured to perform forward error correction (FEC) coding, constellation mapping, and interleaving on the frame; a symbol generator configured to add signaling data to the frame output from the BICM processor to generate an orthogonal frequency division multiplexing (OFDM) symbol; and a transmitter configured to select at least one of a plurality of pilot patterns based on a fast Fourier transform (FFT) size and a guard interval fraction, insert a pilot in the OFDM symbol according to the selected pilot pattern, and transmit a stream including the pilot-inserted OFDM symbol, wherein a maximum length of a predetermined sequence inserted into the OFDM symbol is defined based on an FFT size and a guard interval fraction as shown in a following table.
