An Optimal Resource Allocation Method for Multi-User Multi-Relay DF Cognitive Radio Networks

This letter investigates the resource optimization problem for the multi-user multi-relay decode-forward (DF) cognitive radio networks. The novel optimization metric, namely the bandwidth-power product (BPP), is applied to achieve the optimal spectrum sharing. The formulated problem is found to be a...
