Claim Text:
1. A transmitting apparatus comprising: a frame generator configured to generate a frame comprising 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 components comprising a bootstrap, a preamble, and a payload, and wherein the GI inserter inserts first GIs having a size corresponding to a fast Fourier transform (FFT) size of each of the OFDM symbols of the payload into a front end of each of the OFDM symbols of the payload, inserts second GIs having a size corresponding to a quotient into a front end of each of the first GIs, the quotient being obtained by dividing an extra part of the frame calculated based on the FFT size of each of the OFDM symbols of the payload, the number of the OFDM symbols of the payload, and the size of the first GIs by the number of the OFDM symbols of the payload, and inserts a cyclic postfix (CP) having a size corresponding to a remainder by dividing the extra part of the frame by the number of the OFDM symbols of the payload into a rear end of a final OFDM symbol among the OFDM symbols of the payload.
