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…
Groupcast Index Coding Problem: Joint Extensions
Chinmayananda Arunachala, B. Sundar Rajan
The groupcast index coding problem is the most general version of the classical index coding problem, where any receiver can demand messages that are also demanded by other receive…
On the Optimal Broadcast Rate of the Two-Sender Unicast Index Coding Problem with Fully-Participated Interactions
Chinmayananda Arunachala, Vaneet Aggarwal, B. Sundar Rajan
The problem of two-sender unicast index coding consists of two senders and a set of receivers. Each receiver demands a unique message and possesses some of the messages demanded by…
Optimal Linear Broadcast Rates of the Two-Sender Unicast Index Coding Problem with Fully-Participated Interactions
Chinmayananda Arunachala, Vaneet Aggarwal, B. Sundar Rajan
The two-sender unicast index coding problem consists of finding optimal coded transmissions from the two senders which collectively know the messages demanded by all the receivers.…
Optimal Scalar Linear Codes for Some Classes of The Two-Sender Groupcast Index Coding Problem
Chinmayananda A., B. Sundar Rajan
The two-sender groupcast index coding problem (TGICP) consists of a set of receivers, where all the messages demanded by the set of receivers are distributed among the two senders.…
Wireless Bidirectional Relaying using Physical Layer Network Coding with Heterogeneous PSK Modulation
Chinmayananda A., Saket D. Buch, B. Sundar Rajan
In bidirectional relaying using Physical Layer Network Coding (PLNC), it is generally assumed that users employ same modulation schemes in the Multiple Access phase. However, as ob…
