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.

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

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

Joint time-frequency interference alignment in the frequency-selective Gaussian interference channel
Tongxin xuebao, 2011 To make up for the limitation that the traditional interference alignment can only align the signal in one dimensional domain,a novel joint time-frequency interference alignment scheme was put forward in the frequency-selective Gaussian interference ...

UAV-RIS-Aided Space-Air-Ground Integrated Network: Interference Alignment Design and DoF Analysis [PDF]
IEEE Transactions on Wireless Communications, 2023 In space-air-ground integrated networks (SAGIN), receivers experience diverse interference from both the satellite and terrestrial transmitters. The heterogeneous structure of SAGIN poses challenges for traditional interference management (IM) schemes to

Interactive Interference Alignment [PDF]
IEEE Journal on Selected Areas in Communications, 2013 We study interference channels (IFC) where interaction among sources and destinations is enabled, e.g., both sources and destinations can talk to each other using full-duplex radios. The interaction can come in two ways: 1) {\em In-band interaction:} sources and destinations can transmit and listen in the same channel simultaneously, enabling ...
