Abstract
In this paper, we discuss on the realization of reduced peak power transmis sion for the multicarrier systems. Since the signals have large amplitude f luctuations in conventional multicarrier systems, signals amplified by a no nlinear amplifier are greatly distorted, resulting in severe performance de gradation. In order to avoid this large amplitude fluctuation, we propose a scheme for reducing the nonlinear distortion by using the set of the signa l point series which show low peak to mean envelope power ratio (PMEPR) val ue. In this system, one symbol is transmitted with multicarriers and the re ceived signal is detected with maximum likelihood sequence detection.
