ABSTRACT:
An OFDM signal frame generator includes a rate determiner configured to determine rate information to generate a signal frame to be transmitted as an OFDM signal based on a value of a received signal quality. The signal frame generator further includes a pilot and data arrangement format determiner configured to determine a pilot and data arrangement format of the signal that is to be transmitted; power amplification rate determiner configured to determine a power amplification rate for the signal frame; data symbol generator configured to generate data symbol series to be transmitted based on the rate information and based on the power amplification rate; and transmission signal frame generator configured to generate the signal frame based on the generated data symbol series, on the number of pilot symbols, and based on the pilot & data arrangement format.
