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 ...

Cellular Interference Alignment [PDF]
IEEE 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]
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.

Retrospective interference alignment [PDF]
2011 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]
IEEE 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.

Downlink Interference Alignment [PDF]
IEEE 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.

Asynchronous Interference Alignment [PDF]
IEEE Transactions on Wireless Communications, 2012 A constant K-user interference channel in which the users are not symbol-synchronous is considered. It is shown that the asynchronism among the users facilitates aligning interfering signals at each receiver node while it does not affect the total number of degrees of freedom (DoF) of the channel. To achieve the total K/2 DoF of the channel when single

Asynchronous interference alignment [PDF]
2010 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 ...
