Abstract
A broadcast signal receiver is provided that includes an Orthogonal Frequency Division Multiplexing (OFDM) demodulator configured to OFDM demodulate a received broadcast signal; a pilot detector configured to detect pilots included in the broadcast signal; a frame parser configured to parse a signal frame of the broadcast signal and to output Physical Layer Pipe (PLP) data, the signal frame comprising a bootstrap, a preamble, and a data part; and a decoder configured to perform Forward Error Correction (FEC) decoding on the PLP data. The bootstrap comprises preamble structure information about the preamble. The preamble comprises a plurality of preamble symbols. The preamble carries Layer 1 (L1) signaling data for the signal frame. A first preamble symbol has a minimum number of carriers (NoC) and the first preamble symbol comprises NoC-related information indicating an NoC for at least one remaining preamble symbol.
