Linear Transceiver design for Downlink Multiuser MIMO Systems: Downlink-Interference Duality Approach

open access: yes, 2013
This paper considers linear transceiver design for downlink multiuser multiple-input multiple-output (MIMO) systems. We examine different transceiver design problems. We focus on two groups of design problems.

Power Allocation and Scheduling for SWIPT Systems with Non-linear Energy Harvesting Model

open access: yes, 2016
In this paper, we design a resource allocation algorithm for multiuser simultaneous wireless information and power transfer systems for a realistic non-linear energy harvesting (EH) model. In particular, the algorithm design is formulated as a non-convex

Synchronization and Transient Stability in Power Networks and Non-Uniform Kuramoto Oscillators [PDF]

open access: yes, 2011
Motivated by recent interest for multi-agent systems and smart power grid architectures, we discuss the synchronization problem for the network-reduced model of a power system with non-trivial transfer conductances.

Generalized Scattering Matrix Formulation and its Relationship with TARC and Maximum Power Transfer Theorem

open access: yes
In this paper, we present a rigorous framework for analyzing arbitrary passive matching networks using a generalized Thevenin-Helmholtz equivalent circuit. Unlike prior formulations, which often impose restrictive assumptions such as diagonal matching impedance matrices, our approach accommodates fully passive and interconnected multiport matching ...
