About

Our laboratory conducts research on modulation and demodulation techniques and network technologies based on statistical signal processing to realize next-generation wireless communications with high bit rates and high reliability. Recently, we are also focusing on the application of machine learning on mobile communications.

We welcome those who are interested in wireless communications and who wish to work on the development of future communications technologies that support beyond 5G/6G. We welcome laboratory visits at any time, please feel free to contact us.

key words: MIMO communication, OFDM, Interference cancellation, D2D communication, Machine learning, Adaptive signal processing

Recent research project

Wireless network control using machine learning
Physical layer cryptography
Constant-amplitude OFDM modulation schemes
Polar codes in OFDM systems
Parameter estimation and beam control for hybrid beamforming MU-MIMO Systems
Improvement of pilot contamination problem in Massive MIMO systems
Time-to-digital converter (TDC) with real zero and its application in OFDM systems
Underwater acoustic MIMO-OFDM communication system

We mostly conduct computer simulations to evaluate proposed methods. We often use MATLAB, Python, and C as languages. Please see the RESEARCH ACTIVITIES PAGE for details about our research themes.

Laboratory life

There is no core time and students are only required to attend two lab seminars per week. There are two kinds of seminars in our laboratory: research presentation & book reading.

All members attend research presentation while book reading contains two divided sessions according to student’s grade: elementary reading & senior reading, which relates to basic textbook of wireless communications and Murphy's "Machine Learning: A Probabilistic Perspective", respectively. Presentations in English or Japanese are both OK!

Students will have meetings discussing research issues with professor once per 1~2 weeks after their research topics are decided. As in 2022, meetings are held online, and lab seminars are held in hybrid form. In addition, when good research results are obtained, we proactively present them at domestic and international conferences. In the case of business trips, expenses will be covered by the laboratory.

Laboratory equipment

Students are provided with a personal desk and a desktop PC in their room (Room 918 or 916). In addition, laptop computers (MacBook Pro, etc.) may also be available (but limited number available).

There are more than 10 workstations in the laboratory to provide a smooth simulation environment, and Room 918 has household appliances (electric kettle, refrigerator, microwave oven) and a sofa.

Career paths of graduates

Like the overall trend at Tokyo Tech, many students find employment after graduation from the master's program. Major place of employment includes telecommunications carriers (NTT Docomo, KDDI, Softbank, Rakuten Mobile), Sony, NTT Data, NTT East, NRI, Murata Manufacturing, Amazon, and many others.

Some of our graduates go on to doctoral programs. Not only graduates, but also working students are pursuing their doctoral degrees in our laboratory
