Abstract
A multicarrier transmission apparatus that achieves both power efficiency in a high-frequency amplifier and quality of transmission signal in a radio transmission system in next-generation mobile communications that supports high speed data packet transmission. In the apparatus, adaptive peak limiterperforms adaptive hard limit processing on baseband signals of frequency channels passed through multiplexing sectionstofor users, multicarrier signal generating circuitwith peak suppressing function performs peak limit processing on a synthesized multicarrier signal, hybrid distortion compensating circuitcorrects non-linear distortion due to high-frequency amplifier, and the multicarrier signal is transmitted from an antenna (ANT).
