Abstract (in Japanese) (See Japanese page) 
(in English) The OFCDM(Orthogonal Frequency and Code Division Multiplexing) system is receiving attention to achieve a high data rate transmission for multimedia communication.A problem with the system is that PAPR (Peak to Average Power Ratio) of the OFCDM signal increases as the number of carriers increases.In this paper, we investigate peak reducing methods for OFCDM system.We show that the peak reduction scheme and adaptive predistortion gives a high power efficiency and high linearity in power amplification of OFCDM signal.
