Aligned Interference Neutralization and the Degrees of Freedom of the 2x2x2 Interference Channel
Tiangao Gou, Syed A. Jafar, Sang-Woon Jeon +1
We show that the 2x2x2 interference channel, i.e., the multihop interference channel formed by concatenation of two 2-user interference channels achieves the min-cut outer bound va…
Retrospective Interference Alignment
Hamed Maleki, Syed A. Jafar, Shlomo Shamai
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 p…
Network Coding for Multiple Unicasts: An Interference Alignment Approach
Abhik Das, Sriram Vishwanath, Syed Jafar +1
This paper considers the problem of network coding for multiple unicast connections in networks represented by directed acyclic graphs. The concept of interference alignment, tradi…
Degrees of Freedom Region of a Class of Multi-source Gaussian Relay Networks
Sang-Woon Jeon, Sae-Young Chung, Syed A. Jafar
We study a layered -user -hop Gaussian relay network consisting of nodes in the layer, where and . We observe that the t…
Distributed Data Storage with Minimum Storage Regenerating Codes - Exact and Functional Repair are Asymptotically Equally Efficient
Viveck R. Cadambe, Syed A. Jafar, Hamed Maleki
We consider a set up where a file of size M is stored in n distributed storage nodes, using an (n,k) minimum storage regenerating (MSR) code, i.e., a maximum distance separable (MD…
Aiming Perfectly in the Dark - Blind Interference Alignment through Staggered Antenna Switching
Chenwei Wang, Tiangao Gou, Syed A. Jafar
We propose a blind interference alignment scheme for the vector broadcast channel where the transmitter is equipped with M antennas and there are K receivers, each equipped with a…
