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.
