Abstract
A receiving apparatus for receiving an orthogonal frequency division multiplexing (OFDM) signal including a frame having one frame length of a plurality of patterns. The apparatus comprises an acquiring section to acquire information regarding a preamble signal from an OFDM signal from a transmitting apparatus; a frame determining section to determine whether the one frame length is short in the frame based on the information regarding the acquired preamble signal; and a time interpolating section to obtain transmission path characteristics by comparing a pilot contained in the preamble signal with a known pilot corresponding to the pilot in a phase of transmission, when the frame determining section determines that the one frame length is short in the frame, and to interpolate a data portion in a time direction based on transmission path characteristics.
