<p>An OFDM modulated wave transmitter apparatus wherein a symbol mapping circuit and an S/P converter generate an OFDM symbol signal from transport data. An IFFT, a P/S converting and GI adding circuit, a timing adjusting circuit, a D/A converter, a frequency converter, a local oscillator and an analog filter generate an OFDM modulated wave signal from the OFDM symbol signal. A PA control circuit limits the band of the OFDM symbol signal and generates a power supply control signal and a PA control signal. A PA uses, as the power supply voltage, a voltage supplied from a DC/DC converter and amplifies, based on the PA control signal, and outputs the OFDM modulated wave signal.</p> |
