The Single-Uniprior Index-Coding Problem: The Single-Sender Case and The Multi-Sender Extension
Lawrence Ong, Chin Keong Ho, Fabian Lim
Index coding studies multiterminal source-coding problems where a set of receivers are required to decode multiple (possibly different) messages from a common broadcast, and they e…
Optimal Coding Schemes for the Three-Receiver AWGN Broadcast Channel with Receiver Message Side Information
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
This paper investigates the capacity region of the three-receiver AWGN broadcast channel where the receivers (i) have private-message requests and (ii) may know some of the message…
Coding Schemes for a Class of Receiver Message Side Information in AWGN Broadcast Channels
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
This paper considers the three-receiver AWGN broadcast channel where the receivers (i) have private-message requests and (ii) know some of the messages requested by other receivers…
On Index Coding in Noisy Broadcast Channels with Receiver Message Side Information
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
This letter investigates the role of index coding in the capacity of AWGN broadcast channels with receiver message side information. We first show that index coding is unnecessary…
Linear Codes are Optimal for Index-Coding Instances with Five or Fewer Receivers
Lawrence Ong
We study zero-error unicast index-coding instances, where each receiver must perfectly decode its requested message set, and the message sets requested by any two receivers do not…
The Capacity of Three-Receiver AWGN Broadcast Channels with Receiver Message Side Information
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
This paper investigates the capacity region of three-receiver AWGN broadcast channels where the receivers (i) have private-message requests and (ii) know the messages requested by…
