Research

Master wireless, create communication technology friendly to humans and the earth
As Guglielmo Marconi, the father of wireless communications, said "It is dangerous to put limits on wireless," wireless systems have unlimited potential to enrich our lives. Based on communication theory, network architecture, and signal processing, 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 such as sensor and ad hoc networks, it is crucial to keep connectivity high for delivering more data with low latency, and also to save energy for longer time operation. We are aiming to design and build medium access control and topology control protocols so as to utilize and manage wireless resources efficiently for the use of the emerging IoT or trillion sensors universe.

Theme2:Wireless Sensing

Overview

A sensor which converts physical quantities to electrical signals can be a sensing system and create new services when a lot of sensors are assembling together and connecting each other, besides having processing and communication functions. We are aiming to develop new sensing systems exploiting radio wave propagation characteristics such as localization for mobile objects including sensors and persons, as well as identification, interference and channel estimation.

Theme3:Wireless Communications

Overview

Communication traffic is rapidly growing as widely spreading wireless tools and sensors, which causes wireless resources a critical shortage. In-band full duplex communications can double the capacity in principle than half duplex communications used in current wireless LAN etc., however it must suppress self-interference. We are aiming to develop a self-interference canceler for in-band full duplex radio communication systems that can efficiently utilize wireless resources by spatial-temporal control.
