■ Frequency Utilization Efficiency Improvement by Spectrum Sharing

Research content

Recently, wireless access systems such as Cellular Phone, Wireless LAN, Satellite and IoT, have been growing very rapidly by using their own features. On the other hand, frequency resource has been becoming insufficient for them.
In order to solve this problem, our laboratory researches wireless access technologies to improve frequency utilization efficiency by spectrum sharing among several wireless access systems.
Our research topics are cognitive radio, heterogeneous network, interference compensation, adaptive array antenna, modulation-demodulation and forward error correction and so on.
