A novel technique of reducing the Peak-to-Average Power Ratio (PAPR) of Multi-Carrier (MC) modulated signals is proposed. The method advocated is spectrally efficient, has a low implementational complexity and hence it is also suitable for low-power, portable implementation. Moreover, it was designed to be compatible with existing standard-based Orthogonal Frequency Division Multiplex (OFDM) systems. As an example of the performance of the proposed scheme, the amplifier back-off requirement in a Terrestrial Digital Video Broadcast (DVB-T) system can be reduced from 12 to 6 dB, while satisfying the out-of-band emission specifications imposed by the Federal Communications Commission (FCC) spectral mask.
