An OFDM system with reduced non-linear effect

In this paper, we discuss the realization of reduced peak power transmission for OFDM systems. Since the signals have large amplitude fluctuations in conventional OFDM systems, signals amplified by a non-linear amplifier are greatly distorted, resulting in severe performance degradation. In order to avoid this large amplitude fluctuation, we propose a scheme for reducing the non-linear distortion by using the set of the signal point series which shows low peak-to-mean-envelope-power-ratio (PMEPR) value. In this system, one symbol is transmitted with multicarriers and the received signal is detected with maximum likelihood sequence (MLS) detection
