    Abstract

    This paper discusses the limitation of the phasing technique proposed by Narahashi and Nojima for reducing the PAPR of OFDM symbols. It is shown that although the phasing sequence proposed by Narahashi and Nojima works well for constant amplitude and constant phase angle signals, the technique does not work for inputs with varying phase angles, for example, QPSK. To improve this situation a modified phasing sequence is proposed and numerical results show a very good reduction in PAPR for input symbols with both constant and varying phase angles.
