HF REU students conducted research on high-frequency long-range wireless communications, which allow wireless communication over thousands of kilometers without the need for satellites. They are of immeasurable importance in applications such as military and government communications and public safety and civil service distress communications.
"I can happily say that, after coming in with absolutely no knowledge of communications or artificial intelligence, I now have a firm understanding of how to develop, describe and implement complex systems involving neural networks, reinforcement learning and equalization," said UA ECE undergraduate Celyn Jacobs.
Beyond learning about the technical aspects of wireless communications, students also learned about their multitude of applications, allowing them to gain a new perspective on the field’s importance.
"It hadn’t occurred to me how often the technology in this field is used in our current society," said Emily Huynh, a student at the University of Nevada, Las Vegas. "This experience has taught me how to better understand research papers, read mathematical notations, communicate with my teammates, orient myself when my work is more open ended, and think more flexibly. I believe these skills will have a positive impact on my academic and professional career."
In addition, students honed skills that are important in any career path, such as teamwork and effective communication.
"My favorite part of the HF REU was definitely the moments where a bunch of us – students, mentors, and faculty – might be huddled around a table or whiteboard bouncing ideas off each other nonstop," said Stony Brook University student Christopher Smith. "Being in an environment where people’s ideas interact earnestly and at such a high level was something I’m not sure I’ve ever been a part of, and I really enjoyed it."
Professors Tamal Bose and Loukas Lazos and associate professor Michael Marefat led the HF REU program. Graduate student mentors included Jingcheng Li, Noel Teku and Ziqi Xu.
