RIS-Aided Zero-Forcing and Regularized Zero-Forcing Beamforming in Integrated Information and Energy Delivery [PDF]
IEEE Transactions on Wireless Communications, 2022 This paper considers a network of a multi-antenna array base station (BS) and a reconfigurable intelligent surface (RIS) to deliver both information to information users (IUs) and power to energy users (EUs). The RIS links the connection between the IUs and the BS as there is no direct path between the former and the latter.

Expected propagation time for probabilistic zero forcing [PDF]
, 2022 Zero forcing is a coloring process on a graph that was introduced more than fifteen years ago in several different applications. The goal is to color all the vertices blue by repeated use of a (deterministic) color change rule. Probabilistic zero forcing

Zero-Forcing Processes on Proper Interval Graphs and Twisted Hypercubes [PDF]
, 2023 Zero forcing is a graph infection process where a colour change rule is applied iteratively to a graph and an initial set of vertices, S. If S results in the entire graph becoming infected, we call this set a zero forcing set.

On zero forcing number of graphs and their complements [PDF]
Discrete Mathematics, Algorithms and Applications, 2015 The zero forcing number, Z(G), of a graph G is the minimum cardinality of a set S of black vertices (whereas vertices in V(G)\S are colored white) such that V(G) is turned black after finitely many applications of "the color-change rule": a white vertex is converted to a black vertex if it is the only white neighbor of a black vertex.

, 2022 In this paper, we study minimal (with respect to inclusion) zero forcing sets. We first investigate when a graph can have polynomially or exponentially many distinct minimal zero forcing sets. We also study the maximum size of a minimal zero forcing set $\overline{\operatorname{Z}}(G)$, and relate it to the zero forcing number $\operatorname{Z}(G ...

Improved Signal Detection Techniques for QOSTBC System in Fast Fading Channel
Journal of Telecommunications and Information Technology, 2020 Most existing quasi-orthogonal space time block coding (QO-STBC) schemes have been developed relying on the assumption that the channel is flat or remains static during the length of the code word symbol periods to achieve an optimal antenna diversity ...

Signed zero forcing number and controllability for a networks system with a directed hypercube [PDF]
MATEC Web of Conferences, 2022 The controllability for complex network system is to find the minimum number of leaders for the network system to achieve effective control of the global networks.

Diversity analysis of two-way MIMO relaying system based on zero-forcing [PDF]
, 2012 The two-way multiple-input and multiple-output relay system is investigated in this paper, where bi-directional communications between two source nodes are supported by a relay node with multiple antennas.

0034 | Zero Forcing Number in Neutrosophic Graphs
, 2022 In this book, some notions are introduced about “Zero Forcing Number in Neutrosophic Graphs.” Three chapters are devised as “Common Notions”, “Modified Notions” and “Extended Notions”. Three manuscripts are cited as the references of these chapters which
