Abstract: In this work, we investigate the performance of geometric constellation shaping for highorder coded quadrature amplitude modulation (QAM) over an additive white Gaussian noise (AWGN) channel ...
Abstract: In this letter, a linearity-enhanced Doherty power amplifier (DPA) design strategy based on input second-harmonics control is proposed. By combining the load modulation process and analyzing ...
NIMS, in joint research with the University of Tokyo, AIST, the University of Osaka, and Tohoku University, have proposed a ...
