Opportunistic Relay Selection with Cooperative Macro Diversity

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
We apply a fully opportunistic relay selection scheme to study cooperative diversity in a semianalytical manner. In our framework, idle Mobile Stations (MSs) are capable of being used as Relay Stations (RSs) and no relaying is required if the direct path

Physical layer security of relay selection MF wireless systems over Nakagami fading channels

open access: yesDianxin kexue
In response to the poor performance of physical layer security (PLS) in the existing modify and forward (MF) wireless systems and the limitations of their channel modeling, a PLS model for relay selection MF wireless systems with maximal ratio combining (

Performance of improved decode-and-forward cooperation in low SNR

open access: yesTongxin xuebao, 2010
An enhancement was proposed that the receiving node feeds back its decoding state to the other nodes.Further,the enhancement can improve the performance of decode-and-forward cooperative diversity.The outage probability and throughput of incremental ...

Low-Complexity Relay Selection for Full-Duplex Random Relay Networks

open access: yesMathematics
Full-duplex relay networks have been studied to enhance network performance under the assumption that the number and positions of relay nodes are fixed.
