Subcarrier-Pair Based Resource Allocation for Cooperative AF Multi-Relay OFDM Systems
We study the joint allocation of three types of resources, namely, power, subcarriers and relay nodes, in cooperative two-hop multi-relay OFDM systems. Each relay adopts the amplif...

Cooperation strategies for secrecy in MIMO relay networks with unknown eavesdropper CSI
We investigate secure communications for a four-node relayeavesdropper channel with multiple data stream transmission, assuming that the eavesdropper’s channel state information...
