Interference alignment by motion [PDF]
Proceedings of the 19th annual international conference on Mobile computing & networking - MobiCom '13, 2013 Recent years have witnessed increasing interest in interference alignment which has been demonstrated to deliver gains for wireless networks both analytically and empirically. Typically, interference alignment is achieved by having a MIMO sender precode its transmission to align it at the receiver.

Opportunistic downlink interference alignment [PDF]
2014 IEEE International Symposium on Information Theory, 2014 In this paper, we propose an opportunistic downlink interference alignment (ODIA) for interference-limited cellular downlink, which intelligently combines user scheduling and downlink IA techniques. The proposed ODIA not only efficiently reduces the effect of inter-cell interference from other-cell base stations (BSs) but also eliminates intra-cell ...

Channel aided interference alignment [PDF]
IET Signal Processing, 2017 Interference alignment (IA) techniques mostly attain their degrees of freedom benefits as the number of channel extensions tends to infinity. Intuitively, the more interfering signals that need to be aligned, the larger the number of dimensions needed to align them. This requirement poses a major challenge for IA in practical systems.

On optimal ergodic interference alignment [PDF]
2012 IEEE Global Communications Conference (GLOBECOM), 2012 The original ergodic interference alignment scheme proposed by Nazer et al. requires symmetric channel phase distribution. In this paper, we investigate a new ergodic interference alignment scheme which can achieve one half interference-free degree of freedom (DoF) for arbitrary phase distribution. Even for symmetric phase distributions, the new scheme

Interference alignment with limited feedback [PDF]
2009 IEEE International Symposium on Information Theory, 2009 We consider single-antenna interference networks where M sources, each with an average transmit power of P/M, communicate with M destinations over frequency-selective channels (with L taps each) and each destination has perfect knowledge of its channels from each of the sources.

A nonlinear approach to interference alignment [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 Cadambe and Jafar (CJ) alignment strategy for the K-user scalar frequency-selective fading Gaussian channel, with encoding over blocks of 2n+1 random channel coefficients (subcarriers) is considered. The linear zero-forcing (LZF) strategy is compared with a novel approach based on lattice alignment and lattice decoding (LD).

Opportunistic interference alignment in MIMO interference channels [PDF]
2008 IEEE 19th International Symposium on Personal, Indoor and Mobile Radio Communications, 2008 We present two interference alignment techniques such that an opportunistic point-to-point multiple input multiple output (MIMO) link can reuse, without generating any additional interference, the same frequency band of a similar pre-existing primary link. In this scenario, we exploit the fact that under power constraints, although each radio maximizes

International Journal of Distributed Sensor Networks, 2018 This article aims to optimize the information rate of a cognitive radio network with multiple secondary users. A primary user rate optimization approach based on dichotomy of the degree of freedom is proposed, where the primary users’ eigenmodes are ...
