Cellular Interference Alignment [PDF]

open access: yesIEEE Transactions on Information Theory, 2014
Interference alignment promises that, in Gaussian interference channels, each link can support half of a degree of freedom (DoF) per pair of transmit-receive antennas. However, in general, this result requires to precode the data bearing signals over a signal space of asymptotically large diversity, e.g., over an infinite number of dimensions for time ...

Strong Interference Alignment [PDF]

open access: yesWireless Personal Communications, 2020
Interference alignment (IA) adjusts signaling scheme such that all interfering signals are squeezed in interference subspace. IA mostly achieves its performance via infinite extension of the channel, which is a major challenge for IA in practical systems.

Retrospective interference alignment [PDF]

open access: yes2011 IEEE International Symposium on Information Theory Proceedings, 2011
We explore similarities and differences in recent works on blind interference alignment under different models such as staggered block fading model and the delayed CSIT model. In particular we explore the possibility of achieving interference alignment with delayed CSIT when the transmitters are distributed.

Interference Alignment for Secrecy [PDF]

open access: yesIEEE Transactions on Information Theory, 2011
This paper studies the frequency/time selective $K$-user Gaussian interference channel with secrecy constraints. Two distinct models, namely the interference channel with confidential messages and the one with an external eavesdropper, are analyzed.

Resource Allocation in User-Centric Optical Wireless Cellular Networks Based on Blind Interference Alignment

open access: yesJournal of Lightwave Technology, 2021
Visible light communications (VLC) have been recently proposed to enhance the capacity of next generation of wireless services. Moreover, VLC networks usually comprise a large number of overlapping optical access points (APs). Moreover, each of these APs

Asynchronous interference alignment [PDF]

open access: yes2010 48th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2010
A constant three-user interference channel wherein users are not symbol synchronous is considered. A novel practical interference alignment scheme for this channel is proposed wherein aligning interfering signals at each receiver is performed with the help of asynchronous delays which inherently exist among the received signals at each receiver node ...

An Anti-Turbulence Self-Alignment Method for SINS under Unknown Latitude Conditions

open access: yesSensors, 2022
For the alignment problem of strapdown inertial navigation system (SINS) under the complex environment of unknown latitude, angular oscillation interference, and line interference, the ant colony simulated annealing algorithm of gravity vector ...

Joint Interference Alignment and Power Allocation Based on Stackelberg Game in Device-to-Device Communications Underlying Cellular Networks

open access: yesIEEE Access, 2021
As a promising wireless communication technique, Device-to-Device (D2D) can improve the utilization of spectrum resources, overall system throughput and reduce end-to-end delay, energy consumption by exploiting the direct radio link between local devices.

Downlink Interference Alignment [PDF]

open access: yesIEEE Transactions on Communications, 2010
We develop an interference alignment (IA) technique for a downlink cellular system. In the uplink, IA schemes need channel-state-information exchange across base-stations of different cells, but our downlink IA technique requires feedback only within a cell.

Joint Interference Alignment and Probabilistic Caching in MIMO Small-Cell Networks

open access: yesIEEE Transactions on Vehicular Technology, 2021
Cache-enabled small base stations (SBS) are capable of relieving the heavy burden of the backhaul link and reducing the transmission latency. The hit probability depends on the coverage probability and caching placement probabilities.
