Relays represent a promising approach to extend the cell coverage, combat the strong shadowing effects as well as guarantee the QoS in dense networks. Among the numerous existing ...
— In this paper, two different feedback configurations of the relay channel are investigated. Specifically, in our first configuration, the source node in a relay channel is ...
Relay-based cooperative communications can achieve spatial diversity gains, enhance coverage and potentially increase capacity. If considered for large networks, traditional relayi...
Abstract— This paper discusses channel estimation in a cooperative orthogonal frequency-division multiplexing (OFDM) network in the presence of frequency offsets. Both the amplif...
We consider a Gaussian two-hop network where the source and the destination can communicate only via a relay node who is both an eavesdropper and a Byzantine adversary. Both the s...
