Abstract (in Japanese) (See Japanese page) 
(in English) The EER transmission system was introduced to
exploit high efficiency switching power amplifiers in the high
PAPR transmission systems such as QAM and OFDM. However,
due to transient attenuation characteristics of the tuned switching
power amplifiers, EER systems suffered from low power effi-
ciency in the actual transmission systems. EPWM architecture
was introduced to improve power efficiency of the EER system by
avoiding slow transient attenuation of input current of switching
power amplifier. However, EPWM architecture had a problem
of high peak switch voltage and low power efficiency.
This paper proposes a novel EPWM-EER architecture which
improves peak switch voltage and power efficiency of the conven-
tional EPWM architecture with keeping faster transient atten-
uation than the conventional EER architecture. ADS simulation
results show that the proposed EPWM-EER architecture has
higher power efficiency than the conventional EPWM architec-
ture and faster transient attenuation than the conventional EER
architecture
