Opportunistic Relaying in Wireless Networks

  title={Opportunistic Relaying in Wireless Networks},
  author={Shengshan Cui and Alexander M. Haimovich and Oren Somekh and H. Vincent Poor},
  journal={IEEE Transactions on Information Theory},
Relay networks having n source-to-destination pairs and m half-duplex relays, all operating in the same frequency band and in the presence of block fading, are analyzed. This setup has attracted significant attention, and several relaying protocols have been reported in the literature. However, most of the proposed solutions require either centrally coordinated scheduling or detailed channel state information (CSI) at the transmitter side. Here, an opportunistic relaying scheme is proposed that… CONTINUE READING
