Interference-Aware Cooperative Anti-Jamming Distributed Channel Selection in UAV Communication Networks

open access: yesApplied Sciences, 2018
This paper investigates the cooperative anti-jamming distributed channel selection problem in UAV communication networks. Considering the existence of malicious jamming and co-channel interference, we design an interference-aware cooperative anti-jamming

Channel aided interference alignment [PDF]

open access: yesIET Signal Processing, 2017
Interference alignment (IA) techniques mostly attain their degrees of freedom benefits as the number of channel extensions tends to infinity. Intuitively, the more interfering signals that need to be aligned, the larger the number of dimensions needed to align them. This requirement poses a major challenge for IA in practical systems.

A layered caching architecture for the interference channel [PDF]

open access: yesInternational Symposium on Information Theory, 2016
Recent work has studied the benefits of caching in the interference channel, particularly by placing caches at the transmitters. In this paper, we study the two-user Gaussian interference channel in which caches are placed at both the transmitters and ...

Opportunistic interference alignment in MIMO interference channels [PDF]

open access: yes2008 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

Interference channels with strong secrecy [PDF]

open access: yes2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009
It is known that given the real sum of two independent uniformly distributed lattice points from the same nested lattice codebook, the eavesdropper can obtain at most 1 bit of information per channel regarding the value of one of the lattice points.

Topological Interference Management for Wireless Networks

open access: yesIEEE Access, 2018
Topological interference management (TIM) is considered under the condition that only topology-related information is available at the transmitters, but no accurate channel state information is fed back to them, which is capable of significantly reducing

Interference channel with intermittent feedback [PDF]

open access: yes2013 IEEE International Symposium on Information Theory, 2013
We investigate how to exploit intermittent feedback for interference management. Focusing on the two-user linear deterministic interference channel, we completely characterize the capacity region. We find that the characterization only depends on the forward channel parameters and the marginal probability distribution of each feedback link.

On the capacity of MIMO interference channels [PDF]

open access: yes2008 46th Annual Allerton Conference on Communication, Control, and Computing, 2008
The capacity region of a multiple-input-multiple-output interference channel (MIMO IC) where the channel matrices are square and invertible is studied. The capacity region for strong interference is established where the definition of strong interference parallels that of scalar channels.

Content Delivery in Fog-Aided Small-Cell Systems with Offline and Online Caching: An Information—Theoretic Analysis

open access: yesEntropy, 2017
The storage of frequently requested multimedia content at small-cell base stations (BSs) can reduce the load of macro-BSs without relying on high-speed backhaul links. In this work, the optimal operation of a system consisting of a cache-aided small-cell
