CTH17-2: Energy-efficient cooperative relaying over fading channels with simple relay selection

Madan, R K ; Mehta, N B ; Molisch, Andreas LU and Zhang, J (2006) IEEE Global Telecommunications Conference, 2006
Abstract
We consider a cooperative wireless network where the source broadcasts data to relays, some or all of which cooperatively beamform to forward the data to the destination. The network is subject to an overall outage constraint. We generalize the standard approaches for cooperative communications in two respects: (i) we explicitly model and factor in the cost of acquiring

channel state information (CSI), and (ii) we consider more general, yet simple, selection rules for the relays and compute the optimal one among them. These rules include as special cases several relay selection criteria proposed in the literature. We present analytical results for the

homogeneous case, where the links have identical mean channel gains.... (More)

Numerical results show that while the cost of training and feedback of CSI is significant, relay cooperation is still beneficial. (Less)
