| Abstract(in English) | In this paper, we discuss the realization of reduced peak power transmission for the OFDM(Orthogonal Frequency Division Multiplexing)systems.Since the signals have large amplitude fluctuations in conventional OFDM systems, signals amplified by a nonlinear amplifier are greatly distorted, resulting in severe performance degradation.In order to avoid the large amplitude fluctuations, we propose a scheme for reducing the nonlinear distortion by using the phase series which shows minimum PMEPR(Peak to Mean Envelope Power Ratio).In this system, one symbol is transmitted with multicarriers and the received signal is detected with maximum likelihood sequence detection. |
