Power Allocation for Goodput Optimization in BICM-OFDM Systems [PDF]
2008 IEEE International Conference on Communications, 2008 This paper deals with the power allocation problem for coded multicarrier transmission. Specifically, we focus on a bit interleaved coded modulation (BICM) packet transmission implemented with orthogonal frequency division multiplexing (OFDM) and in the presence of automatic repeat request (ARQ) protocol.

EURASIP Journal on Wireless Communications and Networking, 2009 The power allocation problem for multiuser wireless networks is considered under the assumption of amplify-and-forward cooperative diversity. Specifically, optimal centralized and distributed power allocation strategies with and without minimum rate ...

The Optimal Allocation of Power in Organizations [PDF]
, 2000 Starting from the separation between formal and real authority, the paper considers a hierarchical relation where delegation of control can be used as an incentive mechanism. It shows that delegation is optimal when parties' interests are neither too divergent nor too close.

Distributed beamforming and power allocation for cooperative networks. [PDF]
, 2008 Cooperative diversity systems rely on using relay nodes to relay copies of transmitted information to the destination such that each copy experiences different channel fading, hence increasing the diversity of the system.

Optimal Power Allocation in Spatial Modulation Systems
IEEE Transactions on Wireless Communications, 2017 In spatial modulation (SM) systems, when channel state information is available at the transmitter, adaptive power allocation can be exploited to enhance the SM performance. In this paper, optimal power allocation in SM systems is considered from an information-theoretical view.
