| Outline of Final Research Achievements |
In view of growing interest toward high speed yet green information and communication technology (ICT), this research has targeted realizatiion of advanced communications systems that can simultaneously achieve high energy efficiency and high bandwidth efficiency. Our major contributions include: 1) foundation of theory that reveals trade-off between power efficiency, and bandwidth efficiency for given acceptable nonlinear distortion considering power amplifier efficiency of transmitter circuit; and 2) development and evaluation of wireless communications systems that can achieve better trade-off in terms of power and bandwidth efficiency.
