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 limiter400performs adaptive hard limit processing on baseband signals of frequency channels passed through multiplexing sections200ato200dfor users, multicarrier signal generating circuit500with peak suppressing function performs peak limit processing on a synthesized multicarrier signal, hybrid distortion compensating circuit700corrects non-linear distortion due to high-frequency amplifier32,and the multicarrier signal is transmitted from an antenna (ANT).
