Interference alignment and cancellation [PDF]
ACM SIGCOMM Computer Communication Review, 2009 The throughput of existing MIMO LANs is limited by the number of antennas on the AP. This paper shows how to overcome this limit. It presents interference alignment and cancellation (IAC), a new approach for decoding concurrent sender-receiver pairs in MIMO networks.

A Novel Joint Power and Feedback Bit Allocation Interference Alignment Scheme for Wireless Sensor Networks [PDF]
Sensors, 2017 It is necessary to improve the energy efficiency of batteries in wireless sensor networks (WSNs). The multiple-input multiple-output (MIMO) technique has become an important means to ameliorate WSNs, and interference management is the core of improving ...

Interference alignment for the MIMO interference channel
, 2014 We study vector space interference alignment for the MIMO interference channel with no time or frequency diversity, and no symbol extensions. We prove both necessary and sufficient conditions for alignment.

On Feasibility of Interference Alignment in MIMO Interference Networks [PDF]
IEEE Transactions on Signal Processing, 2010 We explore the feasibility of interference alignment in signal vector space -- based only on beamforming -- for K-user MIMO interference channels. Our main contribution is to relate the feasibility issue to the problem of determining the solvability of a multivariate polynomial system, considered extensively in algebraic geometry. It is well known, e.g.

Outlier-Resistant Initial Alignment of DVL-Aided SINS Using Mahalanobis Distance [PDF]
SensorsDue to the influence of the complex underwater environment, the initial alignment method for Doppler velocity log (DVL)-aided strap-down inertial navigation systems (SINS) often suffer from performance degradation, especially when DVL measurements are ...

Interference Alignment Testbeds [PDF]
IEEE Communications Magazine, 2017 Interference alignment has triggered high impact research in wireless communications since it was proposed nearly 10 years ago. However, the vast majority of research is centered on the theory of interference alignment and is hardly feasible in view of the existing state-of-the-art wireless technologies.

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 ...

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 ...

Strong Interference Alignment [PDF]
Wireless Personal Communications, 2020 Interference alignment (IA) adjusts signaling scheme such that all interfering signals are squeezed in interference subspace, and obtains the maximum degrees of freedom in an interference channel. However, IA mostly achieves its performance via infinite extension of the channel, which is a major challenge in practical systems.
