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 ...

Fractional Zero Forcing via Three-Color Forcing Games [PDF]
Discrete Applied Mathematics, 2016 An r-fold analogue of the positive semidefinite zero forcing process that is carried out on the r-blowup of a graph is introduced and used to define the fractional positive semidefinite forcing number.

Zero Forcing and Maximum Nullity for Hypergraphs [PDF]
Discrete Applied Mathematics, 2020 The concept of zero forcing is extended from graphs to uniform hypergraphs in analogy with the way zero forcing was defined as an upper bound for the maximum nullity of the family of symmetric matrices whose nonzero pattern of entries is described by a given graph: A family of symmetric hypermatrices is associated with a uniform hypergraph and zeros ...

Prior Zero Forcing for Cognitive Relaying
IEEE Transactions on Wireless Communications, 2013Relaying primary signals by cognitive base-stations (CBSs) can help the primary system and thus win CBSs a higher chance to transmit their own signals. For this purpose, conventional zero-forcing (CZF) beamforming is a straightforward solution where the primary and cognitive signals are transmitted from a multi-antenna CBS without causing interference ...

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.

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.

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.
