Hasegawa Lab
Machine-translated · View original
A lab that makes wireless communications highly efficient using AI and quantum computation.
AboutAbout the lab
Highly efficient wireless communications through AI and quantum computation.
The Hasegawa Lab applies artificial intelligence, quantum computation, and other approaches to wireless communications, conducting research aimed at making Beyond 5G / 6G and IoT systems more efficient and more reliable.
It studies methods for using radio efficiently even in environments where many terminals, such as smartphones and IoT devices, communicate at the same time, and in situations where the communication environment changes.
Topics range widely from fundamentals to applications, including optimization of wireless resource allocation, transmission timing control, high-density IoT, and wireless communications for robots and cybernetic avatars.
The lab also collaborates with other universities, research institutions, and companies, carrying out theoretical studies, simulation, implementation, and experimental evaluation.
Key terms
