Abstract

OFDM (orthogonal frequency division multiplexing) has emerged as one of the best modulations for broadband mobile communications. Despite its robustness against multipath interference, the drawback of peak-to-average power ratio (PAPR) has to be overcome. PAPR increases the A/D and D/A complexity and reduces the high power amplifier efficiency as well as battery life. A new technique for reducing the PAPR of OFDM modulation is presented. This method does not spread the OFDM signal bandwidth, it scarcely increases the computational complexity and no additional information has to be known by the receiver.
