Three Stories on a Two-sided Coin: Index Coding, Locally Recoverable Distributed Storage, and Guessing Games on Graphs
Fatemeh Arbabjolfaei, Young-Han Kim
Three science and engineering problems of recent interests -index coding, locally recoverable distributed storage, and guessing games on graphs- are discussed and the connection be…
Distributed Decode-Forward for Relay Networks
Sung Hoon Lim, Kwang Taik Kim, Young-Han Kim
A new coding scheme for general N-node relay networks is presented for unicast, multicast, and broadcast. The proposed distributed decode-forward scheme combines and generalizes Ma…
The Approximate Capacity of the MIMO Relay Channel
Xianglan Jin, Young-Han Kim
Capacity bounds are studied for the multiple-antenna complex Gaussian relay channel with t1 transmitting antennas at the sender, r2 receiving and t2 transmitting antennas at the re…
Partial Decode-Forward Relaying for the Gaussian Two-Hop Relay Network
Jing Li, Young-Han Kim
The multicast capacity of the Gaussian two-hop relay network with one source, relays, and destinations is studied. It is shown that a careful modification of the partial de…
Structural Properties of Index Coding Capacity Using Fractional Graph Theory
Fatemeh Arbabjolfaei, Young-Han Kim
The capacity region of the index coding problem is characterized through the notion of confusion graph and its fractional chromatic number. Based on this multiletter characterizati…
On Critical Index Coding Problems
Fatemeh Arbabjolfaei, Young-Han Kim
The question of under what condition some side information for index coding can be removed without affecting the capacity region is studied, which was originally posed by Tahmasbi,…
