| Abstract(in English) | A major problem in OFDM(Orthogonal Frequency Division Multiplex) is Inter-Modulation distortion(IM) due to nonlinear power amplification. In this study, we propose to employ a different spreading code on each subcarrier. Employing a different spreading code, the worse chips that suffer from severer IM distortion is dispersed. We also propose a simple formulation for selecting good set of spreading code. We show the validity of our proposal by computer simulation. |
