Abstract
A receiving apparatus receives an Orthogonal Frequency Division Multiplexing (OFDM) signal, including an OFDM symbol, subject to frequency hopping on multiple bands, the OFDM symbol, which functions as a channel estimation sequence, being transmitted multiple times at hopping intervals in a time division manner on each of the bands. The apparatus includes a receiving section for receiving the OFDM signal transmitted on a channel, a Fourier transform section for demultiplexing the OFDM signal into signals of sub-carriers, a channel correcting section for estimating a channel characteristic by using the OFDM symbol functioning as a channel estimation sequence resulting from the demultiplexing into sub-carrier signals and performing channel correction thereon, and a decoding section for performing symbol identification and decoding on the channel-corrected data signal back to the original data signal.
