News:
11/29/2023: Prof. Chih-Chun Wang will be elevated to IEEE Fellow in January 1, 2024.
11/29/2023: I am looking for graduate research assistance on streaming codes and low latency multi-hop communications, starting in fall 2024. The research directions will be related to the following papers published by the Ph.D. students of Prof. Wang: #1, #2, #3, #4, #5.
01/28/2020: Chih-Hua Chang’s paper is accepted for publication in ICC.
01/29/2017: I am looking for graduate research assistance on delay-constrained network analysis and protocol design.
08/21/2014: I am looking for graduate research assistance working on two possible projects: Project 1: Capacity characterization of practical network coding (reference 1, reference 2); and Project 2: Real-time network communications. (reference 1, reference 2). For application, please contact me by email and set up an appointment.
Research Interests:
Network coding: Graph-theoretic capacity characterization of inter-session network coding, algorithmic applications of network coding, Shannon capacity characterization of wireless network coding, network coded feedback, and network-coding protocol design and implementation.
Coding Theory: Iterative decoding algorithms, low-density parity-check (LDPC) codes, multi-phase multi-level codes, soft decoding algorithm for Reed-Solomon codes.
Information and Communication Theory: Multi-user detection using graph-based BP algorithms, dirty paper codes, and network information theory.
Signal Processing: turbo equalization and space time codes.
Control Theory: Optimal stopping theory.
Current Ph.D. students:
Pin-Wen Su (since 2017) working on delay-oriented channel coding.
Wonjun Lee (since 2021) working on delay-oriented control for cyber-physical systems.
Giles Bischoff (since 2021) working on low latency communication systems.
