Abstract :
Centralized algorithms for relay selection and power allocation in cooperative networks have been widely considered in the literature. As effective as the proposed algorithms are, the complexity of centralized implementation and feedback required to communicate the required channel state information makes these solutions impractical. Here we investigate, in terms of the achievable rates for the nodes, relaying and power allocation for cooperative networks and consider the effects of partial channel state information. We first consider 1-bit knowledge of relevant channels followed by the multi-bit case. We also consider the case of multiple sources wherein relay resources must be sub-divided amongst the sources.
