Research

Master wireless, create communication technology friendly to humans and the earth.
Wireless systems have unlimited potential to enrich our lives. Based on communication theory, signal processing, and network architecture, we aim to create communication schemes and network control schemes, as well as novel wireless systems, that connect people to people, people to things, and things to things, and make effective use of limited wireless resources such as frequency and energy.

Theme1:Wireless Networks

Overview

In wireless networks, especially distributed autonomous networks, it is crucial to keep connectivity high for delivering more data with low latency, and also to save energy for longer time operation. Our goal is to design and build resource-efficient protocols for media access control and topology control used in the IoT and the associated digital society, where a vast number of things are connected.

Theme2:Wireless Sensing

Overview

Sensors that convert physical quantities to electrical signals can form sensing systems and create new services when they are equipped with processing and communication functions and when they are collected and connected. Our goal is to develop new sensing systems, such as localization and device identification of moving objects, by exploiting radio wave propagation characteristics as well as nonlinear characteristics of RF components.

Theme3:In-band Full-duplex Wireless

Overview

With the widespread use of wireless devices and sensors, and the rapid increase in communication traffic, wireless resources are in a critical shortage. In-band full duplex communications can double the capacity in principle compared to half duplex communications used in current wireless LANs, etc., however self-interference must be suppressed. Our goal is to develop a self-interference canceller based on the nonlinearity of radio-frequency (RF) circuits to realize in-band full-duplex wireless.
