Optimal Weakly Secure Linear Codes for Some Classes of the Two-Sender Index Coding Problem
Chinmayananda Arunachala, B. Sundar Rajan
The two-sender unicast index coding problem is the most fundamental multi-sender index coding problem. The two senders collectively cater to the demands of all the receivers, by ta…
On the Optimality of Ali-Niesen Decentralized Coded Caching Scheme With and Without Error Correction
Nujoom Sageer Karat, B. Sundar Rajan
The decentralized coded caching was introduced in [M.~A. Maddah-Ali and U.~Niesen, `Decentralized coded caching attains order-optimal memory-rate tradeoff,' \emph{IEEE/ACM Trans. N…
Reduced Complexity Index Codes and Improved Upperbound on Broadcast Rate for Neighboring Interference Problems
Mahesh Babu Vaddi, B. Sundar Rajan
A single unicast index coding problem (SUICP) with symmetric neighboring interference (SNI) has messages and receivers, the th receiver wanting the th message…
A Generalisation of Interlinked Cycle Structures and Their Index Coding Capacity
Mahesh Babu Vaddi, B. Sundar Rajan
Cycles and Cliques in a side-information graph reduce the number of transmissions required in an index coding problem. Thapa, Ong and Johnson defined a more general form of overlap…
A Relation Between Weight Enumerating Function and Number of Full Rank Sub-matrices
Mahesh Babu Vaddi, B. Sundar Rajan
In most of the network coding problems with messages, the existence of binary network coding solution over depends on the existence of adequate sets of -dimen…
An Optimal Linear Error Correcting Delivery Scheme for Coded Caching with Shared Caches
Nujoom Sageer Karat, Spandan Dey, Anoop Thomas +1
Classical coded caching setting avails each user to have one dedicated cache. This is generalized to a more general shared cache scheme and the exact expression for the worst case…
