Two groups of students led by Dr. Hovannes Kulhandjian of Department of Electrical and Computer Engineering in the Lyles College of Engineering in Fresno State will compete in the Beyond 5G Software Defined Radios University Challenge April 27 to 29 in Dayton, Ohio.
In collaboration with the Air Force Research Laboratory, the Wright Brothers Institute hosts the annual challenge, designed to enable students to work together to develop solutions to detection and networking problems using software-defined radios and networks.
Selected teams received software-defined radio kits along with training materials to help prepare for the challenge. The winning team or teams will receive a total of $ 12,000 in cash prizes.
“Our students’ research on SDR-based radio frequency fingerprints and multi-user visible light communications could have a strong impact on the next generation of new technological developments that could be used by military and commercial applications.” , said Kulhandjian.
Group One students will demonstrate the ability to receive radio frequency fingerprints based on artificial intelligence, identifying reliable and unknown sources of radio emissions in communication systems. The radio frequency fingerprint has many applications, including military, which can be used to detect malicious attacks – cloning radio frequency devices.
Group Two students will demonstrate a multi-user optical wireless communication system using SDR. High-speed data is visualized in intensity using visible light and transmitted through a light-emitting diode (a photosensor is used at the end of the receiver to decode the transmitted information).
Optical wireless communication, also known as light-fidelity or LiFi, has many useful applications, including providing high-speed data communications on airplanes, buses, medical facilities, and indoor environments where LED light sources are present. LiFi technology is more secure than WiFi, as it is directional and reduces the likelihood of an attacker stealing communications.
Kulhandjian said he hopes students will use the research and practical experience gained from these projects and apply them to their careers and / or postgraduate studies.
For Vahae Ohanian, a graduate student in electrical engineering, participating in the competition is an honor and validates the time and effort that he and his team have put into this project.
“We all firmly believe that what we are working on can have a huge impact on the future, and being able to show our steps to make this future a reality is an experience we were really trying to do,” Ohanian said.
The two Fresno State teams, one in collaboration with the University of Massachusetts Boston, are among the 10 universities selected to compete in this year’s challenge along with the University of Cincinnati, University of Houston, University of Massachusetts Dartmouth, North Carolina State University, Texas A&M Commerce, Worcester Polytechnic Institute and Wright State University.
The two projects were presented during the oral presentation of the 43rd Annual Research Symposium in Central California. In addition, the team submitted a research paper to the Advanced Photonics Congress, which will be held on July 24-28 in the Netherlands.
“I think my favorite part of this project is showing it in material and seeing the reactions on people’s faces and being able to see and hear the excitement and wonder when they want to learn more about technology,” he said. Ohanian. “Knowing that I was this person just a few months ago and being able to relive and share those feelings again with an audience is always such a wonder and a wonderful byproduct of working with technology and theories that are not yet common. ».
