Journal ArticleDOI
On Optimal Power Allocation for Downlink Non-Orthogonal Multiple Access Systems
TL;DR: In this article, the authors investigated the optimal power allocation with given channel assignment over multiple channels under different performance criteria, namely, maximin fairness, weighted sum rate maximization, sum rate minimization with quality of service (QoS) constraints, and energy efficiency maximization with weights or QoS constraints in downlink NOMA systems.
Journal ArticleDOI
Coordinated Beamforming for Energy Efficient Transmission in Multicell Multiuser Systems
TL;DR: This paper proposes to first transform the original problem into an equivalent optimization problem in a parametric subtractive form, by which the solution is reached through a two-layer optimization scheme, and develops an iterative algorithm to solve it.
Journal ArticleDOI
Coordinated Multicell Multiuser Precoding for Maximizing Weighted Sum Energy Efficiency
TL;DR: This paper investigates energy efficient multicell multiuser precoding design and considers a new criterion of weighted sum energy efficiency, which is defined as the weighted sum of the energy efficiencies of multiple cells.
Journal ArticleDOI
Blind Calibration and DOA Estimation With Uniform Circular Arrays in the Presence of Mutual Coupling
TL;DR: In this paper, a subspace-based blind calibration method for uniform circular arrays is proposed, which uses the incident signals to carry out both direction of arrival (DOA) estimation and array calibration simultaneously.
Journal ArticleDOI
Distributed Multicell Beamforming With Limited Intercell Coordination
TL;DR: Results illustrate that the proposed scheme can achieve near-optimal performance even with a few iterations, hence providing a good tradeoff between performance and backhaul consumption.
