Power Allocation Strategies across N Orthogonal Channels at Both Source and Relay
Youngwook Ko, Masoud Ardakani, Sergiy A. Vorobyov · IEEE Transactions on Communications · 2012
A wireless relay network with one source, one relay and one destination is considered, where nodes communicate via N orthogonal channels. We develop optimal power allocation strategies at both the source and relay for maximizing the overall source-destination capacity under individual power constraints at the source and relay. Some properties of the optimal solution are studied.
