On Resource Allocation in Fading Multiple Access Channels - An Efficient Approximate Projection Approach [PDF]
, 2008 We consider the problem of rate and power allocation in a multiple-access channel. Our objective is to obtain rate and power allocation policies that maximize a general concave utility function of average transmission rates on the information theoretic ...

Energy-efficient power allocation for point-to-point MIMO systems over the rayleigh fading channel [PDF]
, 2012 It is well-established that transmitting at full power is the most spectral-efficient power allocation strategy for point-to-point (P2P) multi-input multi-output (MIMO) systems, however, can this strategy be energy efficient as well?

On the endogenous allocation of decision powers in federal structures [PDF]
Journal of Urban Economics, 2005 Abstract This paper provides a political-economy explanation of the degree of centralization in economic policy making. To determine which policies are to be centralized, regions select representatives who then negotiate the degree of centralization and the regional cost shares of centrally decided policies.

Power Allocation for D2D Communications With SWIPT
IEEE Transactions on Wireless Communications, 2020 Power allocation plays a vital role in coordinating interference between Device-to-Device (D2D) and cellular communications, and when power allocation meets simultaneous wireless information and power transfer (SWIPT), the energy efficiency of D2D communications can be significantly improved.
