Capacity results for binary fading interference channels with delayed CSIT

A Vahid, MA Maddah-Ali… - IEEE Transactions on …, 2014‏ - ieeexplore.ieee.org
To study the effect of lack of up-to-date channel state information at the transmitters (CSITs),
we consider two-user binary fading interference channels with Delayed-CSIT. We …

Resolving the feedback bottleneck of multi-antenna coded caching

E Lampiris, A Bazco-Nogueras… - IEEE Transactions on …, 2021‏ - ieeexplore.ieee.org
Multi-antenna cache-aided wireless networks were thought to suffer from a severe feedback
bottleneck, since achieving the maximal Degrees-of-Freedom (DoF) performance required …

[HTML][HTML] Evaluating ecohydrological model sensitivity to input variability with an information-theory-based approach

MA Farahani, A Vahid, AE Goodwell - Entropy, 2022‏ - mdpi.com
Ecohydrological models vary in their sensitivity to forcing data and use available information
to different extents. We focus on the impact of forcing precision on ecohydrological model …

Binary fading interference channel with no CSIT

A Vahid, MA Maddah-Ali… - IEEE Transactions on …, 2017‏ - ieeexplore.ieee.org
We study the capacity region of the two-user binary fading (or erasure) interference channel,
where the transmitters have no knowledge of the channel state information. We develop new …

Erasure broadcast channels with intermittent feedback

A Vahid, SC Lin, IH Wang - IEEE Transactions on …, 2021‏ - ieeexplore.ieee.org
Achievable data rates in wireless systems rely heavily on the available channel state
information (CSI) throughout the network. However, feedback links, which provide this …

Two-way networks: When adaptation is useless

Z Cheng, N Devroye - IEEE Transactions on Information Theory, 2013‏ - ieeexplore.ieee.org
Most wireless communication networks are two-way, where nodes act as both sources and
destinations of messages. This allows for adaptation at or interaction between the nodes-a …

Approximate capacity region of the MISO broadcast channels with delayed CSIT

A Vahid, MA Maddah-Ali… - IEEE Transactions on …, 2016‏ - ieeexplore.ieee.org
We consider the problem of multiple-input single-output broadcast channels with Rayleigh
fading where the transmitter has access to delayed knowledge of the channel state …

Two-way interference channels

C Suh, IH Wang, D Tse - 2012 IEEE International Symposium …, 2012‏ - ieeexplore.ieee.org
We consider two-way interference channels (ICs) where forward and backward channels
are ICs but not necessarily the same. We first consider a scenario where there are only two …
