A Cognitive Radio TV Prototype For Effective TV Spectrum Sharing

Published in IEEE DySPAN, 2017

This paper demonstrated a prototype of Wireless Local Area Network with dynamic spectrum access in TV spectrum under Cog-TV framework. It shows that with TV set feedback enabled in next generation TV standard, ATSC 3.0, secondary users could evacuate wirelss channels in real-time without significant degradation of TV user experience.

Electronic Design Training Program, 2005-2007

Undergraduate course, Undergraduate Innovation Center, University of Electronic Science and Technology of China, 2007

This was a 2-year extra-curricular training program for 100+ undergraduate students selected from university wide, directly funded by the university administration. From 2005 to 2007, the program was ran by about 20 professors, 3 stuff members, and 8 student teaching assistants (all former trainees). 6 and 10 teams (3 students per team) won the national 1st and 2nd prizes, respectively, in 2007 National Undergraduate Electronic Design Contest.

Multi-Agent System, Fall 2017

Graduate/undergraduate course, University of Nebraska-Lincoln, Department of Computer Science and Engineering, 2017

As the only graduate teaching assistant, I helped Prof. Leen-Kiat Soh in the interactive learning sessions (Game Days), in which over 20 students work in teams to learn strategies in different settings by interacting with other teams. My job was to setup an online website developed by previous TAs, and helped in preparing Game Day reports afterwards.

Data Structure and Algorithms, Fall 2017

Undergraduate course, University of Nebraska-Lincoln, Department of Computer Science and Engineering, 2017

I work as graduate teaching assistant with about 10 undergraduate TAs to assist Prof. Charles Riedesel in grading and tutoring over 40 students from Jeffery S. Raikes School of Computer Science and Management. Meanwhile, I assisted in organizing 4 hackathon events for ACM 2017 North Central North American Regional Contest as the practical session of this course,
