Abstract(in English) | This study investigates the peak-to-average power ratio (PAPR) of multi-carrier CDMA systems with various binary spreading sequences in order to provide smaller PAPR and better transmission characteristics in the nonlinear channel to achieve the high efficiency of power amplifier. As spreading sequences, Golay complementary sequences have the smallest PAPR compared with the derivations of M-sequences. This paper shows that the amplifier can be operated at its saturation point by properly selecting the spreading sequence and that we can save the power by several dB than conventional approach which is operated in the linear region. |
