Joint Optimization of Handover Control and Power Allocation Based on Multi-Agent Deep Reinforcement Learning

IEEE Transactions on Vehicular Technology, 2020
In this paper, we study the handover (HO), and power allocation problem in a two-tier heterogeneous network (HetNet), which consists of a macro base station, and some millimeter-wave (mmWave) small base stations.

The Power of Dynamic Asset Allocation

The Journal of Portfolio Management, 2014
This article re-assesses the evidence and practical relevance of asset returns’ long-horizon predictability, investigating whether practitioners can profitably exploit predictability patterns by using relatively simple, dynamic asset allocation strategies.

AI Based Power Allocation for NOMA

Wireless Personal Communications, 2022
Novel methods using artificial intelligence for downlink power allocation problem in non-orthogonal multiple access networks are presented. The proposed machine learning and deep learning based methods achieved performance close to the optimum in terms of sum capacity with significantly lower computational costs. The numerical results also demonstrated

Adaptive subcarrier allocation, power control, and power allocation for multiuser FDD-DMT systems

2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004
This paper considers the problem of adaptive subcarrier allocation, power control, and power allocation for multiuser frequency division duplex-discrete multitone (FDD-DMT) systems in a Gaussian interference channel. Assuming perfect knowledge of all channel and crosstalk transfer functions, we formulate the problem as an optimization problem to ...
