Optimization of Switch Allocation Problems in Power Distribution Networks

open access: yesJournal of Sensor and Actuator Networks, 2022
This paper presents the implementation of the mono-objective Switch Allocation Problem (SAP) optimization model for electric power distribution networks, considering the equivalent interruption duration per consumer unit EIDCU and non-distributed energy END reliability indexes.

Joint subchannel power allocation for downlink NOMA systems based on quantum carnivorous plant algorithm

open access: yesJournal of King Saud University: Computer and Information Sciences
Currently, most existing research on non-orthogonal multiple access (NOMA) systems converts power allocation into two independent procedures, i.e., inter-subchannel power allocation and intra-subchannel power allocation.

Power allocation under per-antenna power constraints in multiuser MIMO systems

open access: yesTongxin xuebao, 2012
A low-complexity power allocation algorithm was investigated under per-antenna power constraints(PAPC)in multiuser multiple-input multiple-output (MIMO) systems.It was shown that the optimal power allocation subject to PAPC,aimed at maximizing the sum ...

Optimal power allocation for LTE users with different modulations [PDF]

open access: yes2016 Annual IEEE Systems Conference (SysCon), 2016
In this paper, we demonstrate the optimal power allocation for QPSK, 16-QAM, and 64-QAM modulation schedules and the role of channel quality indicator (CQI). We used sigmoidal-like utility functions to represent the probability of successful reception of packets at user equipment (UE).
