ABSTRACT:
A transmitting device is provided that generates OFDM symbols by identifying a sampling frequency of input data that is input from an external device, determining a number of inverse Fourier transform sample points and a number of sampling points of a redundant data portion in accordance with the identified sampling frequency, and subjecting the input data to OFDM modulation using the determined number of sampling points. The transmitting device then transmits the generated OFDM symbols.
