Energy efficient switching between data transmission and energy harvesting for cooperative cognitive relaying systems

Miridakis, Nikolaos I.; Tsiftsis, Theodoros A.; Alexandropoulos, George C.; Debbah, Merouane (Institute of Electrical and Electronics Engineers Inc., 2016-07-12)

A dual-hop cognitive (secondary) relaying system incorporating collaborative spectrum sensing to opportunistically switch between data transmission and energy harvesting is introduced. The secondary relays, first scan the ...
Outage Probability Analysis of Multi-Relay Delay-Limited Hybrid-ARQ Channels

Maham, Behrouz; Hjorungnes, Are; Debbah, Merouane (2010 IEEE 72nd Vehicular Technology Conference - Fall, 2010)

We consider a wireless relay network with with hybrid-automatic retransmission request (HARQ) and Rayleigh fading channels. In this paper, we analyze the outage probability of the multi-relay delay-limited HARQ system with ...
