Optimal Index Codes via a Duality between Index Coding and Network Coding
Ashok Choudhary, Vamsi Krishna Gummadi, Prasad Krishnan
In Index Coding, the goal is to use a broadcast channel as efficiently as possible to communicate information from a source to multiple receivers which can possess some of the info…
An Improved Secretive Coded Caching Scheme exploiting Common Demands
Hari Hara Suthan C, Ishani Chugh, Prasad Krishnan
Coded caching schemes on broadcast networks with user caches help to offload traffic from peak times to off-peak times by prefetching information from the server to the users durin…
Index Coding: Rank-Invariant Extensions
Vamsi Krishna Gummadi, Ashok Choudhary, Prasad Krishnan
An index coding (IC) problem consisting of a server and multiple receivers with different side-information and demand sets can be equivalently represented using a fitting matrix. A…
Rate Index Coding: Forbidden and Feasible Configurations
V. Lalitha, Prasad Krishnan
Linear index coding can be formulated as an interference alignment problem, in which precoding vectors of the minimum possible length are to be assigned to the messages in such a w…
Uniprior Index Coding
Vijaya Kumar Mareedu, Prasad Krishnan
The index coding problem is a problem of efficient broadcasting with side-information. We look at the uniprior index coding problem, in which the receivers have disjoint side-infor…
