Clustering for Interference Alignment in Multiuser Interference Network

IEEE Transactions on Vehicular Technology, 2014
Interference alignment (IA) has been shown to be a promising technique for achieving the optimal capacity scaling of a multiuser interference channel at asymptotically high-signal-to-noise ratio (SNR). However, in practical communication systems, mitigating interference from all interferers via IA is not necessary since some users' interference have ...

Clustering for Interference Alignment in a Multiuser Interference Channel

2012 IEEE 75th Vehicular Technology Conference (VTC Spring), 2012
Interference alignment (IA) has been shown as a promising technique to achieve the optimal capacity scaling of a multiuser interference channel at asymptotically high signal-to-noise-ratio (SNR). However, in practical communication systems, mitigating all interference via IA is not necessary since some of them only have negligible effect due to path ...

Interference alignment in MIMO interference relay channels

2012 IEEE Wireless Communications and Networking Conference (WCNC), 2012
The degrees of freedom (DoF) has been recognized as a powerful metric to characterize the capacity of interference channels in the high signal-to-noise (SNR) region. In this paper, by utilizing linear interference alignment, we investigate the DoF of multiple-input and multiple-output (MIMO) interference relay channels without symbol extensions.

A sufficient condition for interference alignment

2015 IEEE International Symposium on Information Theory (ISIT), 2015
We consider the classical problem of spatial interference alignment (IA) in MIMO channels with constant channel coefficients through design of linear transmit precoders and receiver filters. Some easily (polynomial time) computable necessary conditions for IA have been derived in the literature [1], [2], [3].

Information alignment for consensus with interference

2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014
This paper studies distributed averaging of arbitrary vectors in the presence of network interference by casting an algebraic structure over the interference. While communicating locally with its neighbors for consensus, each agent causes an additive interference, lying on a low-dimensional subspace, in other communication links.

Integer-forcing interference alignment

2013 IEEE International Symposium on Information Theory, 2013
In this paper, we propose a novel framework, integer-forcing interference alignment, that can simultaneously exploit both signal-space and signal-scale alignment. We consider receivers that can decode integer-linear combinations of desired and interfering streams and then solve for their desired symbols.

Polar alignment for interference networks

2011 49th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2011
Polar coding has originally been introduced as a capacity achieving low complexity code for binary input symmetric channels. Polar codes can be understood as transformations that replace a probabilistic channel with parallel deterministic counterparts.

Performance of 5GNR with Interference Alignment

2019 International Conference on Communications, Signal Processing, and their Applications (ICCSPA), 2019
Recently, a New Radio (NR) structure has been proposed for fifth generation (5G) mobile radio systems to support higher data rates and low latency scenarios. In this paper, we investigate the performance of 5G New Radio (5GNR) using precoding for Interference Alignment (IA).

A Review on Interference Alignment in Multiuser Interference Channels

Wireless Personal Communications, 2015
As the density of base stations in wireless networks becomes higher, system performance is limited not by noise but by interference from other transmitters and so research on interference channels has been actively undertaken. In this article, we study interference alignment (IA) techniques, which are known to maximize the achievable degrees of freedom

On the Robustness of Lattice Interference Alignment

IEEE Transactions on Information Theory, 2013
A static (constant channel gains) real K-user interference channel is considered, where all interference (cross) channel gains are integers. For such channels, previous results demonstrate that the number of degrees of freedom is very sensitive to slight variations in the direct channel gains. In this paper, we derive an achievable rate region for such
