    Abstract: A transmitting apparatus is provided. The transmitting apparatus includes: a frame generator configured to generate a frame including a plurality of orthogonal frequency-division multiplexing (OFDM) symbols; and a guard interval (GI) inserter configured to insert GIs into the generated frame, wherein the plurality of OFDM symbols are divided into a bootstrap, a preamble, and a payload, and the GI inserter inserts first GIs having a size corresponding to a fast Fourier transform (FFT) size of each of OFDM symbols configuring the payload into front ends of each of the OFDM symbols, inserts second GIs having a size corresponding to a quotient obtained by dividing an extra region of the payload calculated based on the FFT size of the OFDM symbols configuring the payload, the number of OFDM symbols, and the size of the first GIs by the number of OFDM symbols into front ends of each of the first GIs, and inserts a cyclic postfix (CP) having a size corresponding to the remainder remaining after dividing the extra region of the payload by the number of OFDM symbols into a rear end of a final OFDM symbol configuring the payload.
