| Outline of Final Research Achievements |
In recent years, mobile data traffic and devices have been increasing rapidly. Thus advanced signal processing techniques for wireless communications are required. In this research, we aim to develop adaptive signal processing techniques for power-efficient wireless communication systems utilizing massive antenna technologies. We have proposed adaptive peak cancellation techniques and clarified that it achieves lower per-antenna peak power while significantly reducing computational complexity compared with state-of-arts. In addition, we have proposed interference management and coordination techniques for heterogeneous wireless networks using massive antennas and clarified that it achieves higher system sum-rate than those of state-of-arts. Furthermore, we have proposed analog-to-digital convention techniques and related channel estimation techniques for low-power consumption wireless receivers and clarified the effectiveness of these techniques.
