On Extremal Graphs for Zero Forcing Number
Graphs and Combinatorics, 2022For a graph \(G\) with \(S\subseteq V(G)\), \(S\) is a zero forcing set of \(G\) if iteratively adding vertices to \(S\) from \(V(G)\setminus S\) that are the unique neighbor in \(V(G)\setminus S\) of some vertex in \(S\), results in the entire \(V(G)\) of \(G\).

NOMA With Zero-Forcing V-BLAST
IEEE Communications Letters, 2020In this study, power-domain non-orthogonal multiple access (NOMA) is combined with zero-forcing (ZF) vertical Bell Labs layered space-time (V-BLAST) technique. Motivated by the fact that the successive interference cancellation (SIC) is a pivotal element in either technique, we thoroughly investigate the impact of SIC on inter-user and inter-layer ...

Robust transmit zero-forcing filters
ITG Workshop on Smart Antennas (IEEE Cat. No.04EX802), 2005We present linear and nonlinear robust transmit zero-forcing filters for the downlink of multiuser multiple-input single-output (MU-MISO) time-division-duplex (TDD) systems which are robust with respect to errors in the channel state information (CSI) arising from channel estimation and time lags in mobile communications.

The Performance of Zero Forcing DSL Systems
IEEE Signal Processing Letters, 2013DSL systems use multi-channel processing to mitigate the electromagnetic coupling between the wires in a binder and provide high data rates to multiple users. In recent years, most multichannel processing for DSL had focused on zero-forcing (ZF) processing that was proven to be near optimal.

On the Zero Forcing Number of Bijection Graphs
2016The zero forcing number of a graph is a graph parameter based on a color change process, which starts with a state, where all vertices are colored either black or white. In the next step a white vertex turns black, if it is the only white neighbor of some black vertex, and this step is then iterated.

Coordinated beamforming with relaxed zero forcing
2011 International Conference on Wireless Communications and Signal Processing (WCSP), 2011In this paper, a new beam design paradigm for coordinated beamforming (CB) for current and future cellular networks is proposed based on a relaxed zero-forcing (RZF) constraint. In the conventional zero-forcing (ZF) CB, each cooperating transmitter designs its transmit beamforming matrix to null out interference to undesired receivers completely.

The Complexity of the Positive Semidefinite Zero Forcing
2014The positive zero forcing number of a graph is a graph parameter that arises from a non-traditional type of graph colouring, and is related to a more conventional version of zero forcing. We establish a relation between the zero forcing and the fast-mixed searching, which implies some NP-completeness results for the zero forcing problem.

Zero-Forcing and MMSE Precoding for G.fast
2015 IEEE Global Communications Conference (GLOBECOM), 2014Hybrid copper/fiber networks bridge the gap between the fiber link at the distribution point and the customer by using copper wires over the last meters. The G.fast transmission technology has been designed to be used in such a fiber to the distribution point (FTTdp) network.
