Greedy power allocation for multicarrier systems with reduced complexity [PDF]

open access: yes, 2010
In this paper we consider a reduced complexity discrete bit loading for Multicarrier systems based on the greedy power allocation (GPA) under the constraints of transmit power budget, target BER, and maximum permissible QAM modulation order.

Optimal Power Allocation for Secure Estimation of Multiple Parameters [PDF]

open access: yesIEEE Signal Processing Letters, 2021
Optimal power allocation for secure estimation of multiple deterministic parameters is investigated under a total power constraint. The goal is to minimize the Cramer-Rao lower bound (CRLB) at an intended receiver while keeping estimation errors at an eavesdropper above specified target levels.

A note on power allocation for optimal capacity

open access: yesCoRR, 2022
The problems of determining the optimal power allocation, within maximum power bounds, to (i) maximize the minimum Shannon capacity, and (ii) minimize the weighted latency are considered. In the first case, the global optima can be achieved in polynomial time by solving a sequence of linear programs (LP).

A new low-cost discrete bit loading using greedy power allocation [PDF]

open access: yes, 2009
In this paper we consider a low cost bit loading based on the greedy power allocation (GPA). Compared to the standard GPA, which is optimal in terms of maximising the data throughput, three suboptimal schemes are suggested, which perform GPA on subsets ...

Optimal power allocation for DL NOMA systems

open access: yes2017 25th Signal Processing and Communications Applications Conference (SIU), 2017
Non-orthogonal multiple access (NOMA) is an important candidate for 5G radio access technology. In NOMA transmitter, different users' signals are superposed on the same radio resource with different power allocation factors. The receiver removes other users' signals from the received signal before decoding its own signal.

Optimal and sub‐optimal rate and power allocation for random networks

open access: yesTransactions on Emerging Telecommunications Technologies, 2023
AbstractWe consider the power and rate allocation for a transmission in a wireless network where the transmitter knows the channel state of the desired receiver but only knows the statistics of the interferes. While this scenario is often encountered in practice, and extremely important in dense networks, its optimal solution was not yet known.

Multiobjective Optimization Model for Wind Power Allocation

open access: yesMathematical Problems in Engineering, 2017
There is an increasing need for the injection to the grid of renewable energy; therefore, to evaluate the optimal location of new renewable generation is an important task. The primary purpose of this work is to develop a multiobjective optimization model that permits finding multiple trade‐off solutions for the location of new wind power resources. It
