Introduction to Takada Lab.

Recent Research Topics / Facilities of the Lab / Life in the Lab / Research Partners / Study Guide for International Students

We study the wireless communications and the applied radio instrumentations. As well, we involve in the international development projects. Many different approaches are taken, such as fabrication and prototyping, field measurement, lab experiments, computer simulation, and field work.

Recent Research Topics

We focus on the radiowave propagation for wireless communications. Many joint researches are ongoing with industry, research institutions, and other universities.

Radiowave propagation and channel characterization

1. Measurement and modeling of microscopic schattering phenomena in micro- and pico-cell environments
2. Multipath parameter estimation and modeling based on maximum likelihood estimation
3. UWB double directional channel measurement and modeling in short range indoor environment
4. Spatio-temporal channel measurement and modeling for adaptive array and MIMO transmission

Antennas

1. Adaptive antenna impedance matching proximity to human body
2. Analog RF adaptive array antenna using varactors
3. CCI suppression property of handset adaptive array antenna
4. Spatial fading emulator
5. Evaluation of UWB transmission considering waveform distortion due to antenna

Signal processing and applications

1. Radio surveillance system utilizing independent component analysis
2. Direction of arrival estimation based on amplitude-only array output
3. Realtime telemetry system for monitoring of wild animals
4. MIMO transceiver implementation using software radio approach

International development projects

1. Sustainable development management in the World Cultural Heritage areas
2. Radpidly deployable rural communication systems for regional development

Recent research results are found on publication list.

Life in the Lab

Once a week (Monday, 9:30-13:00), we have a meeting to discuss the recent research results. This seminar is conducted in English.

From April until July, intensive lectures on antennas and propagation are given by Prof. Takada twice a week (Tuesday and Friday, 10:40-13:00). After the summer vacation, individual seminars shall be held for each of the study groups.

Individual research guidance and discussion are available based on the request from students at any time.

Mobile Communication Research Group （Laboratories of Prof. Hiroshi Suzuki, Prof. Kiyomichi Araki, Assoc. Prof. Kazuhiko Fukawa, Assoc. Prof. Hidekazu Murata, and Prof. Jun-ichi Takada) has the weekly joint seminar (Monday, 17:30-19:00). Recent topics of each individual lab are usually presented, and distinguished external lecturers are sometimes invited as well.

Topics related to the international development projects are all joint works with Prof. Shinobu Yume Yamaguchi of Global Scientific and Information Center.

We have the monthly party to foster closer relationship. When the party is held in the campus, we enjoy the tastes of students' own countries.

Research Partners

Both official and inofficial partners are listed in alphabetical order.
