BIO

Dr. Xun Zhang, who obtained a B.E. degree from Wuhan university of technology,  an M.E. degree from Université Marrie Pierre Curie in 2005, and PhD from Nancy university in 2009.  He obtained a Post-Doc fellowship of Motorola Foundation in IETR/SCEE at Supélec in 2010.  He is currently employed as an associate professor in MINARC team of the laboratory  at the Institut Supérieur d’Electronique de Paris (ISEP). His research activities involve algorithm implementation optimization for Visible Light Communication (VLC) and Feedback Systems Control for sleep apnea. He initiated and was strongly involved in a successful project on VLC with Tsinghua University with Professor Jian Song team. The project was granted 4 years funding from both China and France. During this project, he organized a workshop on the VLC in September 2015 and Special Session in ISCAS 2016. He is now working with an international consortium to submit a Horizon 2020 project. He is author and co-author of 20 conference papers, 3 journals, and 2 book chapters. He also co-chaired special sessions in IEEE international conferences (NEWCAS, FTFC).

Research Expertise and Scholarly Interest: 

Research expertise in the primary area of electronic/digital/RF system design, covering:

  • High performance and high speed signal processing for electronic and digital design on FPGA
  • Digital Signal Processing
  • Software Defined Radio (SDR) on FPGA
  • system implementation: on Android and customized hardware platforms.

Funding and Consultancy Projects:
  • Principle investigator & project leader in ISEP – 2017-2020, H2020 project on “Internet of Radio-Light” (€575,000). The IoRL project is to provide a broadband radio-light communications solution that operates in unlicensed millimeter wave and visible light spectra, does not suffer from interference because of the propagation characteristics of EM waves in this part of the spectrum and provides universal broadband coverage within buildings from radio-light access points that are pervasively located within the light roses in buildings. This technology can be the network solution for the smart infrastructure and large scale sensor network applied to other indoor environments such as Tube Stations, Underground Pedestrian tunnels etc.

Principle investigator – 2013-2015, Sino-France Innovation Funding project on “ Visible light communication system for hospital environment” ($5,000). This project aims to provide the adaptive network interface design for the indoor positioning ssystems

    Description:

    Usage of light emitting diode (LED) is rapidly growing due to its reliability, low power consumption, and high efficiency. In Visible Light Communication (VLC) system, LED is used for illumination simultaneously it can be used for communication. The objective of this project is to study the VLC system and design a prototype to demonstrate the functionality of VLC system for audio and digital signal transmission through modulated LED light beam. The VLC system consists of two main components which are transmitter and receiver. The transmitter is attached with LED and the receiver is attached with a photodiode, such that, the signal can be transmitted through LED and receive by Photodiode. The design of the VLC system involved an idea of generating negative voltage, signal amplification, compensating background light intensity, recovering the attenuated signal. In this project, two prototypes i.e. VLC audio transmitter and receiver, VLC free space opto-transceiver have been designed and constructed. These prototypes have successfully been demonstrated for transmission of audio signal and digital signal. The VLC audio transmitter and receiver demonstrated the transmission of audio signal from computer to speaker wirelessly and VLC Free space Opo- Transceiver demonstrated the transmission of a digital signal from a computer to computer wirelessly as well. Both prototypes signal are transmitted through visible light. 

    This internship will follow these steps:
    1. Study and compare different VLC algorithms, choose an appropriate algorithm.

    2. Android indoor location application development

  • VLC based Human sensing system design
