Achievable Rate Region of the Bidirectional Buffer-Aided Relay Channel with Block Fading
Vahid Jamali, Nikola Zlatanov, Aissa Ikhlef +1
The bidirectional relay channel, in which two users communicate with each other through a relay node, is a simple but fundamental and practical network architecture. In this paper,…
Asymptotically Optimal Power Allocation for Energy Harvesting Communication Networks
Nikola Zlatanov, Robert Schober, Zoran Hadzi-Velkov
For a general energy harvesting (EH) communication network, i.e., a network where the nodes generate their transmit power through EH, we derive the asymptotically optimal online po…
Adaptive Mode Selection and Power Allocation in Bidirectional Buffer-aided Relay Networks
Vahid Jamali, Nikola Zlatanov, Aissa Ikhlef +1
In this paper, we consider the problem of sum rate maximization in a bidirectional relay network with fading. Hereby, user 1 and user 2 communicate with each other only through a r…
Adaptive Mode Selection in Bidirectional Buffer-aided Relay Networks with Fixed Transmit Powers
Vahid Jamali, Nikola Zlatanov, Aissa Ikhlef +1
We consider a bidirectional network in which two users exchange information with the help of a buffer-aided relay. In such a network without direct link between user 1 and user 2,…
Capacity of the State-Dependent Half-Duplex Relay Channel Without Source-Destination Link
Nikola Zlatanov, Robert Schober
We derive the capacity of the state-dependent half-duplex relay channel without source-destination link. The output of the state-dependent half-duplex relay channel depends on the…
