Research summary
Study of wireless communication technology and signal processing technology useful for safety, security, and the comfort of society, and their applications Wireless communication is not only useful for sending huge amount of data, but is also useful for the safety, security, and comfort of our life. The Wireless Signal Processing Laboratory (WSP Lab.) conducts research on signal processing technology to achieve high-quality wireless communications, for vehicles travelling at high-speed or in places where radio waves are difficult to reach. Specifically, our research is aimed for use in communications equipment for high-speed railways travelling at speeds in excess of several hundred kph and for satellites orbiting several tens of thousands of kilometers above the surface of earth. WSP Lab. also conducts research on the visualization (modeling) of wireless environment that cannot be seen by the human eye. Furthermore, attempts will be made, making use of the results, to nurture seeds of technology that will be useful in areas other than wireless communications using radio waves, such as optical wireless communications and sensors, as well as acoustic communications for underwater communications, where development in the future is expected.
