A Modified Grouped Linear ZF Algorithm Using Different Modulation Schemes for MIMO Systems [PDF]
A new algorithm for a group iterative linear Zero-Forcing (ZF) receiver formultiple-input multiple-output (MIMO) systems is proposed in this paper. Theproposed algorithm merges between the group linear ZF receiver and V-Blastalgorithms, where the signals

Adaptive Modulation for Orthogonal Frequency Division Multiplexing [PDF]
Orthogonal frequency division multiplexing (OFDM) is one of the promising technologies to improve the spectral efficiency, enhance system capacity and mitigate inter-symbol interference in the wireless communication system.

Rate Splitting With Finite Constellations: The Benefits of Interference Exploitation vs Suppression
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.

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

Failed Zero Forcing Numbers of Trees and Circulant Graphs
Given 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 $S$.

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 ...

Zero forcing in iterated line digraphs
Zero forcing is a propagation process on a graph, or digraph, defined in linear algebra to provide a bound for the minimum rank problem. Independently, zero forcing was introduced in physics, computer science and network science, areas where line ...

Rigid Linkages and Partial Zero Forcing
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.

The zero forcing polynomial of a graph
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.
