Research Interest

As required high bandwidth and QoS (Quality of Service) in communications, it is necessary that we enhance capacity of communication systems and interconnect heterogeneous communication networks to provide real-time of high capacity service. In addition, to implement BcN (Broadband convergence Network), it’s needed to realize convergence of wired and wireless networks. In accordance with this trend, we have investigated several applications of wired and wireless communication systems such as OCDM (Optical Code Division Multiplexing), OFDM (Orthogonal Frequency Division Multiplexing), TWDM (Time-Wavelength Division Multiplexing), RoF (Radio over Fiber), VLC (Visible Light Communi- cation), and its applications. We are also studying optical signal processing that overcomes the limitations of electrical signals such as optical fiber sensor, medical diagnosis using optical signals and 3D imaging, etc.
