Sequential slotted amplify-and-forward with partial relay isolation [PDF]
In this paper, we propose a novel relay ordering and scheduling strategy for the sequential slotted amplify-and-forward (SAF) protocol and evaluate its performance in terms of diversity-multiplexing trade-off (DMT).

Power Allocation for Cognitive Collaborative Network Based on Adaptive Relay [PDF]
In relayed transmission systems,power allocation algorithm based on Decode and Forward(DF) increases error in case of incorrect decoding of the information symbols,and the one based on Amplify Forward(AF) amplifies the noise.In order to solve the problem,

Pattern Division Multiple Access Featuring Amplify-and-Forward Relaying in an Uplink Network
NOMA is one of key enabling technologies for prosumer energy management. We studied co-operative techniques useful for establishing pattern division multiple access (PDMA) in an uplink network. In particular, we examined amplify-and-forward (AF) relaying
