I am an assistant professor at Harbin Institute of Technology (HIT), Shenzhen

Hi, I am Ziyi Xie (谢子怡). Welcome to my page 👋

I am an assistant professor with Harbin Institute of Technology, Shenzhen. I received the PhD degree in information and communication engineering from Harbin Institute of Technology in 2024. Before this, I earned a bachelor’s degree of communication engineering at Harbin Institute of Technology.

My research focuses on performance analysis on wireless communications. The topics include reconfigurable intelligent surfaces, near-field communications, and next-generation multiple access techniques.

If you are interested in my work or in collaborating with me, please feel free to have a discussion with me (ziyi.xie@hit.edu.cn). I am always looking forward to brilliant minds 😊
