Chordal Codes: Code Construction and Efficient Gaussian-Elimination Decoding
Yulin Chen, Laigang Guo, Tong Li +1
Maximum-likelihood decoding of linear codes over erasure channels can be considered as solving a linear system of a column submatrix of the parity-check matrix. In practice, Gaussi…

Routing Optimality for Demand Graphs of Matching Number at Most Two
Xiaohong Cai, Yulin Chen
We prove that network coding and fractional routing have the same capacity region in undirected networks whose demand graph has matching number at most two, that is, when no three…
