A Linearly Convergent Douglas-Rachford Splitting Solver for Markovian Information-Theoretic Optimization Problems
Teng-Hui Huang, Aly El Gamal, Hesham El Gamal
In this work, we propose solving the Information bottleneck (IB) and Privacy Funnel (PF) problems with Douglas-Rachford Splitting methods (DRS). We study a general Markovian inform…
On the Multi-View Information Bottleneck Representation
Teng-Hui Huang, Aly El Gamal, Hesham El Gamal
In this work, we generalize the information bottleneck (IB) approach to the multi-view learning context. The exponentially growing complexity of the optimal representation motivate…
Optimal Wireless Caching with Placement Cost
Yousef AlHassoun, Faisal Alotaibi, Aly El Gamal +1
Coded caching has been shown to result in significant throughput gains, but its gains were proved only by assuming a placement phase with no transmission cost. A free placement pha…
Fundamental Limits of Dynamic Interference Management with Flexible Message Assignments
Tolunay Seyfi, Yasemin Karacora, Aly El Gamal
The problem of interference management is considered in the context of a linear interference network that is subject to long term channel fluctuations due to shadow fading. The fad…
The Role of Transmitter Cooperation in Linear Interference Networks with Block Erasures
Yasemin Karacora, Tolunay Seyfi, Aly El Gamal
In this work, we explore the potential and optimal use of transmitter cooperation in wireless interference networks with deep fading conditions. We consider a linear interference n…
Joint Uplink-Downlink Cell Associations for Interference Networks with Local Connectivity
Manik Singhal, Aly El Gamal
We study information theoretic models of interference networks that consist of K Base Station (BS) - Mobile Terminal (MT) pairs. Each BS is connected to the MT carrying the same in…
Topological Interference Management: Linear Cooperation is not useful for Wyner's Networks
Aly El Gamal
In this work, we study the value of cooperative transmission in wireless networks if no channel state information is available at the transmitters (no CSIT). Our focus is on large…
Degrees of Freedom in Wireless Interference Networks with Cooperative Transmission and Backhaul Load Constraints
Meghana Bande, Aly El Gamal, Venugopal V. Veeravalli
Degrees of freedom (DoF) gains are studied in wireless networks with cooperative transmission under a backhaul load constraint that limits the average number of messages that can b…
Flexible Backhaul Design and Degrees of Freedom for Linear Interference Networks
Aly El Gamal, Venugopal V. Veeravalli
The considered problem is that of maximizing the degrees of freedom (DoF) in cellular downlink, under a backhaul load constraint that limits the number of messages that can be deli…
Dynamic Interference Management
Aly El Gamal, Venugopal V. Veeravalli
A linear interference network is considered. Long-term fluctuations (shadow fading) in the wireless channel can lead to any link being erased with probability p. Each receiver is i…
Interference Channels with Coordinated Multi-Point Transmission: Degrees of Freedom, Message Assignment, and Fractional Reuse
Aly El Gamal, V. Sreekanth Annapureddy, Venugopal V. Veeravalli
Coordinated Multi-Point (CoMP) transmission is an infrastructural enhancement under consideration for next generation wireless networks. In this work, the capacity gain achieved th…
On Optimal Message Assignments for Interference Channels with CoMP Transmission
Aly El Gamal, V. Sreekanth Annapureddy, Venugopal V. Veeravalli
The degrees of freedom (DoF) number of the fully connected K-user Gaussian interference channel is known to be K/2. In [1], the DoF for the same channel model was studied while all…
Degrees of Freedom of Interference Channels with CoMP Transmission and Reception
V. Sreekanth Annapureddy, Aly El Gamal, Venugopal V. Veeravalli
We study the Degrees of Freedom (DoF) of the K-user interference channel with coordinated multi-point (CoMP) transmission and reception. Each message is jointly transmitted by M_t…
Degrees of Freedom (DoF) of Locally Connected Interference Channels with Coordinated Multi-Point (CoMP) Transmission
Aly El Gamal, V. Sreekanth Annapureddy, Venugopal V. Veeravalli
The degrees of freedom (DoF) available for communication provides an analytically tractable way to characterize the information-theoretic capacity of interference channels. In this…
The Two-Way Wiretap Channel: Achievable Regions and Experimental Results
Aly El Gamal, O. Ozan Koyluoglu, Moustafa Youssef +1
This work considers the two-way wiretap channel in which two legitimate users, Alice and Bob, wish to exchange messages securely in the presence of a passive eavesdropper Eve. In t…
