| Abstract(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 distor- tion, we need to design a digital predistortion after analyzing the output characteristic 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 simultaneously amplifying multi-band OFDM signals and design its digital predistortion. Numerical analysis shows our proposed predistortion can improve both EVM and ACPR. |
