Optimization of the Receiving Orientation Angle for Zero-Forcing Precoding in VLC
IEEE Communications Letters, 2021 We study the performance of linear zero-forcing (ZF) precoding in multiuser multiple-input single-output visible light communications (VLC) when we are able to select the receiving orientation angle (ROA) of each user. For radio-frequency communications,

, 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 ...

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.

Zero-Forcing-Based Downlink Virtual MIMO–NOMA Communications in IoT Networks [PDF]
IEEE Internet of Things Journal, 2020 To support massive connectivity and boost spectral efficiency for Internet of Things (IoT), a downlink scheme combining virtual multiple-input–multiple-output (MIMO) and nonorthogonal multiple access (NOMA) is proposed. All the single-antenna IoT devices

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.

Zero-forcing in random regular graphs
Journal of Combinatorics, 2021 The zero forcing process is an iterative graph colouring process in which at each time step a coloured vertex with a single uncoloured neighbour can force this neighbour to become coloured.

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 ...

Communications in Science and Technology, 2021 Impulse noise is the major factor degrading the performance of the wireless system, imposing the need for the impulse noise mitigation strategy. Mainly, in the multiple-input multiple-output (MIMO) and orthogonal frequency-division multiplexing (OFDM ...

Zero forcing in Benzenoid network
Proyecciones (Antofagasta), 2019 A set S of vertices in a graph G is called a dominating set of G if every vertex in V (G)\S is adjacent to some vertex in S. A set S is said to be a power dominating set of G if every vertex in the system is monitored by the set S following a set of rules for power system monitoring.
