In order to improve the energy efficiency of the optical wireless communications, a joint power allocation and relay selection scheme is proposed for a relay assisted non-line-of-sight optical wireless communication system employing coherent detection with a dual optical channel multiplexing technique. The proposed joint power allocation and relay selection scheme aims to improve energy efficiency...
In this work, the performance of two-hop wireless systems under statistical queueing \emph{end-to-end} delay constraints is investigated. In the two-hop links, it is assumed that there is no direct link between the source and destination. The communication between the source and destination is accomplished via an intermediate full-duplex relay node, which forwards the information to the destination...
