Abstract
A technique is proposed to significantly reduce the peak to average power ratio (PAPR) for an OFDM system by stabilizing the signal envelope. By using partial response (PR) signaling to spread each sub-symbol over multiple subcarriers, we first compress the signal in time. The signal is then rearranged such that it is possible to stabilize the envelope, improving the PAPR by up to 5 dB without using excessive time-bandwidth resources. We quantify the improvement in PAPR and system performance in additive white Gaussian noise
