Wireless systems research at Meiji University
Kohei Ohno, Meiji University, Japan

This presentation introduces the researches at our “wireless system laboratory” in Meiji university. We aim to be more convenient using radio technologies, which are not only used for communications but also used for sensing techniques like radars. In this presentation, following research topics will be introduced briefly:
- Spectrum sharing and interference mitigation techniques
- Detection technique for human body in rubbles after earthquake
- Channel and performance evaluation for vehicular networks
Efficient spectrum usage is one of the most significant topics for radio communications. In this presentation, experimental/computer simulation results and proposed schemes are shown. In 2 and 3, the research issues specific in Japan are introduced.

Kohei Ohno was born in 1980 in Tokyo, Japan. He received the B.E. M.E. and Dr. E. degrees from Meiji University, Japan, in 2002, 2004, and 2008 respectively. From 2008 to 2013, he was an assistant professor at Tokyo University of Science. In 2013, he joined the school of interdisciplinary mathematical sciences at Meiji University and he became an associate professor in 2017. He is a guest researcher in TU/e from March 2019. His major interest includes in area of wireless communication, modulation, spread spectrum, ultra-wideband radio and radar systems.


28 GHz dual-polarized active phased array for 5G mm-wave
Teun van den Biggelaar, TU/e

In collaboration with NXP Semiconductors, an 8x8 dual-polarized active phased array has been developed. On the antenna board, 32 of NXP’s analog beamformer ICs can be found. These ICs enable amplitude and phase control of the RF signal fed to each of the antenna elements. The array operates in the 5G mm-wave band (26.5 – 29.5 GHz) and is intended as a first prototype. In the presentation, the design and calibration of the array will be shown. Moreover, the beamforming capabilities of the array will be presented and the challenges in characterizing and calibrating the array will be discussed.

A.J. (Teun) van den Biggelaar received his MSc degree in Electrical Engineering (cum laude) from TU/e, in 2016. He is currently pursuing his PhD degree at the TU/e in Electrical Engineering, with the focus on antenna array calibration techniques for millimeter-wave 5G systems.
