Abstract (in Japanese) (See Japanese page) 
(in English) To realize “Flexible Wireless System” which integrates various wireless systems on a unified hardware platform,
we examine a multi-band power amplifier (PA) toward equipment miniaturization. To compensate for this nonlinear distortion,
we need to design a digital predistortion after analyzing the output characteristc of a wideband PA with a multi-band simultaneous
amplifying. In this paper, we evaluate the error vector magnitude (EVM) and the adjacent channel power ratio (ACPR)
using simultaneouly amplifying multi-band OFDM signals and design its digital predistortion. Numerical analysis shows our
proposed predistortion can improve both EVM and ACPR.
