Orthogonal Frequency Division Multiplexing (OFDM) is an attractive multi-carrier modulation technique as it is immune to frequency selective fading channels, offers high spectral efficiency and offers many other advantages. Although OFDM is an efficient multi-carrier technique, it has a major limitation. The PAPR of a conventional OFDM signal is naturally high. In order to reduce it, many different techniques have been proposed and clipping is one of them. In this paper, the authors employ clipping as the PAPR reduction technique and propose a block diagram designed to reduce PAPR and improve the BER performance.
