1. A transmitting apparatus comprising:
a frame generator configured to generate a frame comprising a plurality of orthogonal frequency division multiplexing (OFDM) symbols;
a processor configured to insert one or more pilots and one or more guard intervals (GIs) into the generated frame; and
a transmitter configured to transmit the frame into which the pilots and the GIs are inserted,
wherein the frame comprises a bootstrap, a preamble and a payload,
wherein the payload comprises one or more subframes,
wherein the one or more subframes are located following the preamble,
wherein a length of a guard interval (GI) inserted in the preamble is equal to a length of a GI inserted in a first subframe from among the one or more subframes, and
wherein a pilot density in the preamble is determined according to the length of the GI inserted in the preamble, the pilot density of the preamble being equal or greater than a pilot density in the first subframe.
