Satoru Aikawa
Professor | Ph.D. in Engineering
Artificial Intelligence and Informatics Course
Communication and Radio-Wave Application Research Group
Drawing on professional experience in Wi-Fi system development, Professor Aikawa brings a practitioner's perspective to the classroom, teaching information theory, digital communication systems, and radio regulations. His courses are built around textbooks he has written for each subject, using visual explanations to make the fundamentals of communication more accessible to students. His research carries the same practical orientation, with a focus on building systems that address real user needs.
Smartphone Navigation Using Wi-Fi Radio Signals
What students can learn
Through this project, students build a working knowledge of communication engineering, machine learning, and application development, gaining direct experience in bringing these disciplines together to design and implement complete, functioning systems.
This research develops a smartphone-based navigation system that draws on existing Wi-Fi signals to estimate a user's location in environments where GPS reception is unavailable, such as underground shopping arcades. By linking a smartphone application with server-side data, the system aims to connect local information with everyday user convenience, supporting broader efforts toward community revitalization.
Vehicle Management Using UWB-Based Distance Estimation
What students can learn
Students develop practical expertise in radio-wave experimentation and communication systems, with particular emphasis on wireless sensing and measurement techniques.
This research applies UWB and other wireless sensing technologies to detect moving objects such as vehicles and estimate their distance, direction, and speed. The resulting techniques may be applied to gate control, parking guidance, and other systems that support mobility management.
