Minhao Cui
I am currently a fifth-year Ph.D. student at Manning College of Information and Computer Sciences, University of Massachusetts Amherst under supervision of Prof. Jie Xiong. I also closely work with Prof. Qing Wang from TU Delft.
My reserach topic is Visible Light Communication, especially for the side-channel of Visible Light Communication systems and Wireless Sensing.

Projects
We utilize the leaked EM signals from the powerline to conduct wireless sensing with the help of human body. The targets only needs to wear a small and cheap ring antenna on their fingers, the proposed system can recognize the motions of the whole body.
We utilize the human body to improve the energy harvesting performance. The wearable bracelet antenna is designed to harvest more leaked energy from the VLC systems with the help of human body.
We utilize the leaked side channel signals of VLC to transmit additional data bits for communication. Without too much hardware modification and energy cost, we can double the data rate of the VLC systems with our novel design.
We utilize the side channel of VLC - a Radio Frequency (RF) channel created unintentionally during the transmission process of VLC - to break the VLC limitations:i) surrounding objects can easily block VLC links, and ii) intense ambient light can saturate the photodiodes of VLC receivers.
In this paper, for the first time, we show that VLC is not as secure as people thought: VLC can be sniffed through walls! The key principle behind this is that in VLC transmissions, a VLC transmitter not only emits visible light signals but also leaks out `side channel RF signals'.
