A Rate Splitting Strategy for Massive MIMO with Imperfect CSIT
Mingbo Dai, Bruno Clerckx, David Gesbert +1
In a multiuser MIMO broadcast channel, the rate performance is affected by the multiuser interference when the Channel State Information at the Transmitter (CSIT) is imperfect. To…
Caching-Aided Coded Multicasting with Multiple Random Requests
Mingyue Ji, Antonia Tulino, Jaime Llorca +1
The capacity of caching networks has received considerable attention in the past few years. A particularly studied setting is the shared link caching network, in which a single sou…
An Efficient Multiple-Groupcast Coded Multicasting Scheme for Finite Fractional Caching
Mingyue Ji, Karthikeyan Shanmugam, Giuseppe Vettigli +3
Coded multicasting has been shown to improve the caching performance of content delivery networks with multiple caches downstream of a common multicast link. However, the schemes t…
Wireless Multihop Device-to-Device Caching Networks
Sang-Woon Jeon, Song-Nam Hong, Mingyue Ji +2
We consider a wireless device-to-device (D2D) network where nodes are uniformly distributed at random over the network area. We let each node with storage capacity cache fi…
An Active-Sensing Approach to Channel Vector Subspace Estimation in mm-Wave Massive MIMO Systems
Saeid Haghighatshoar, Giuseppe Caire
Millimeter-wave (mm-Wave) cellular systems are a promising option for a very high data rate communication because of the large bandwidth available at mm-Wave frequencies. Due to th…
Cooperation Alignment for Distributed Interference Management
Vasilis Ntranos, Mohammad Ali Maddah-Ali, Giuseppe Caire
We consider a cooperative Gaussian interference channel in which each receiver must decode its intended message locally, with the help of cooperation either at the receivers side o…
Channel Vector Subspace Estimation from Low-Dimensional Projections
Saeid Haghighatshoar, Giuseppe Caire
Massive MIMO is a variant of multiuser MIMO where the number of base-station antennas is very large (typically 100), and generally much larger than the number of spatially mult…
Secret key-based Identification and Authentication with a Privacy Constraint
Kittipong Kittichokechai, Giuseppe Caire
We consider the problem of identification and authentication based on secret key generation from some user-generated source data (e.g., a biometric source). The goal is to reliably…
A Hierarchical Rate Splitting Strategy for FDD Massive MIMO under Imperfect CSIT
Mingbo Dai, Bruno Clerckx, David Gesbert +1
In a multiuser MIMO broadcast channel, the rate performance is affected by the multiuser interference when the Channel State Information at the Transmitter (CSIT) is imperfect. To…
Secure Massive MIMO Transmission with an Active Eavesdropper
Yongpeng Wu, Robert Schober, Derrick Wing Kwan Ng +2
In this paper, we investigate secure and reliable transmission strategies for multi-cell multi-user massive multiple-input multiple-output (MIMO) systems with a multi-antenna activ…
On the Role of Transmit Correlation Diversity in Multiuser MIMO Systems
Junyoung Nam, Giuseppe Caire, Young-Jo Ko +1
Correlation across transmit antennas, in multiple antenna systems (MIMO), has been studied in various scenarios and has been shown to be detrimental or provide benefits depending o…
Secure Massive MIMO Transmission in the Presence of an Active Eavesdropper
Yongpeng Wu, Robert Schober, Derrick Wing Kwan Ng +2
In this paper, we investigate secure and reliable transmission strategies for multi-cell multi-user massive multiple-input multiple-output (MIMO) systems in the presence of an acti…
Expanding the Compute-and-Forward Framework: Unequal Powers, Signal Levels, and Multiple Linear Combinations
Bobak Nazer, Viveck Cadambe, Vasilis Ntranos +1
The compute-and-forward framework permits each receiver in a Gaussian network to directly decode a linear combination of the transmitted messages. The resulting linear combinations…
Optimality of Treating Interference as Noise: A Combinatorial Perspective
Xinping Yi, Giuseppe Caire
For single-antenna Gaussian interference channels, we re-formulate the problem of determining the Generalized Degrees of Freedom (GDoF) region achievable by treating interference a…
Order-Optimal Rate of Caching and Coded Multicasting with Random Demands
Mingyue Ji, Antonia M. Tulino, Jaime Llorca +1
We consider the canonical {\em shared link network} formed by a source node, hosting a library of information messages (files), connected via a noiseless common link to des…
