Multiuser Broadcast Erasure Channel with Feedback and Side Information, and Related Index Coding Results
A. Papadopoulos, L. Georgiadis
We consider the N-user broadcast erasure channel with public feedback and side information. Before the beginning of transmission, each receiver knows a function of the messages of…
Message-Passing Algorithms for Optimal Utilization of Cognitive Radio Networks
Hamed Mahmoudi, Georgios Rodolakis, Leonidas Georgiadis +1
Cognitive Radio has been proposed as a key technology to significantly improve spectrum usage in wireless networks by enabling unlicensed users to access unused resource. We presen…
Stable XOR-based Policies for the Broadcast Erasure Channel with Feedback
Sophia Athanasiadou, Marios Gatzianas, Leonidas Georgiadis +1
In this paper we describe a network coding scheme for the Broadcast Erasure Channel with multiple unicast stochastic flows, in the case of a single source transmitting packets to $…
Multiuser broadcast erasure channel with feedback - capacity and algorithms
Marios Gatzianas, Leonidas Georgiadis, Leandros Tassiulas
We consider the -user broadcast erasure channel with unicast sessions (one for each user) where receiver feedback is regularly sent to the transmitter in the form of ACK/NAC…
