Exact MIMO Zero-Forcing Detection Analysis for Transmit-Correlated Rician Fading [PDF]
, 2014 We analyze the performance of multiple input/multiple output (MIMO) communications systems employing spatial multiplexing and zero-forcing detection (ZF).

Theory and Applications of Graphs, 2015 The k-forcing number of a graph is a generalization of the zero forcing number. In this note, we give a greedy algorithm to approximate the k-forcing number of a graph. Using this dynamic approach, we give corollaries which improve upon two theorems from

The zero forcing polynomial of a graph
, 2018 Zero forcing is an iterative graph coloring process, where given a set of initially colored vertices, a colored vertex with a single uncolored neighbor causes that neighbor to become colored.

Beamforming design of sum rate optimization for MU-MISO scenario
上海师范大学学报. 自然科学版, 2015 This paper investigates the beamforming design based on perfect channel state information (CSI) in a multi-user downlink network.The base station (BS) is equipped with multiple antennas while each user is equipped with one antenna.The BS will communicate

Rate Splitting With Finite Constellations: The Benefits of Interference Exploitation vs Suppression
IEEE Open Journal of the Communications Society, 2021 Rate-Splitting (RS) has been shown recently to be a powerful approach for the design of non-orthogonal transmission, multiple access, and interference management strategies in multi-user multi-antenna systems.

Failed Zero Forcing Numbers of Trees and Circulant Graphs
Theory and Applications of GraphsGiven a graph $G$, the zero forcing number of $G$, $Z(G)$, is the smallest cardinality of any set $S$ of vertices on which repeated applications of the forcing rule (described below) results in all vertices being in $S$.

Rigid Linkages and Partial Zero Forcing
The Electronic Journal of Combinatorics, 2019 Connections between vital linkages and zero forcing are established. Specifically, the notion of a rigid linkage is introduced as a special kind of unique linkage and it is shown that spanning forcing paths of a zero forcing process form a spanning rigid linkage and thus a vital linkage.

Tellus: Series A, Dynamic Meteorology and Oceanography, 2022 This paper considers a dynamical system described by a multidimensional state vector x. A component 'x' of x evolves according to 'dx/dt = f'(x). Equilibrium fluctuations are fluctuations of an equilibrium solution x('t') obtained when the system is in ...
