In wireless communications, spectrum is an important resource which has been assigned to existing wireless communication services. However, there are several attractive wireless communication services which have not been deployed due to the lack of available spectrum. The insufficient amount of available spectrum resources is due to the fact that it is a finite resource which has been allocated for wireless services in a fixed manner. This issue is also known as the spectrum scarcity problem.
In our laboratory, we tackle this problem by investigating wireless systems which can utilize the spectrum dynamically, intelligently and politely. Specifically, we are investigating a system which can globally observe the statistics of spectrum utilization in multiple dimensions such as space, time and frequency. In addition, we also develop wireless systems which can utilize the observed information appropriately based on the support by the spectrum observation system.
The aim of our investigation is to achieve flexible and dynamical spectrum allocation which can lead to easier development for new wireless communication services.
In the tenure track program, there is a very attractive and well-arranged situation for a young research to set up their own laboratory. This is because in addition to the leading professor acting as a mentor, there is also a startup budget and a research fund. In addition, there are several other tenure track professors in the same situation so it is easy to consult with them.
In the academic field, we can concentrate on our own interests and tackle our own challenges which is not possible in the industry. Therefore, I will carry out research based on my own beliefs and sensibility. In the university, there are many young students with much potential. I would like to develop friendly competition among them and it should lead to education for the students.
