Fundamental Limits of Coded Caching: Improved Delivery Rate-Cache Capacity Trade-off [PDF]

open access: yes, 2016
A centralized coded caching system, consisting of a server delivering N popular files, each of size F bits, to K users through an error-free shared link, is considered.

Capacity per Unit-Energy of Gaussian Random Many-Access Channels [PDF]

open access: yes, 2020
We consider a Gaussian multiple-access channel with random user activity where the total number of users $\ell_n$ and the average number of active users $k_n$ may be unbounded.

Asymptotic Analysis of MAP Estimation via the Replica Method and Applications to Compressed Sensing [PDF]

open access: yes, 2011
The replica method is a non-rigorous but well-known technique from statistical physics used in the asymptotic analysis of large, random, nonlinear problems.

On the Degrees of freedom of the K-user MISO Interference Channel with imperfect delayed CSIT [PDF]

open access: yes, 2014
This work investigates the degrees of freedom (DoF) of the K-user multiple-input single-output (MISO) interference channel (IC) with imperfect delayed channel state information at the transmitters (dCSIT).

MacWilliams Identities for Terminated Convolutional Codes [PDF]

open access: yes, 2010
Shearer and McEliece [1977] showed that there is no MacWilliams identity for the free distance spectra of orthogonal linear convolutional codes. We show that on the other hand there does exist a MacWilliams identity between the generating functions of ...

On privacy amplification, lossy compression, and their duality to channel coding

open access: yes, 2018
We examine the task of privacy amplification from information-theoretic and coding-theoretic points of view. In the former, we give a one-shot characterization of the optimal rate of privacy amplification against classical adversaries in terms of the ...

Coded Caching for a Large Number Of Users

open access: yes, 2016
Information theoretic analysis of a coded caching system is considered, in which a server with a database of N equal-size files, each F bits long, serves K users.

Decentralized Coded Caching Attains Order-Optimal Memory-Rate Tradeoff [PDF]

open access: yes, 2014
Replicating or caching popular content in memories distributed across the network is a technique to reduce peak network loads. Conventionally, the main performance gain of this caching was thought to result from making part of the requested data ...

Codes between MBR and MSR Points with Exact Repair Property

open access: yes, 2013
In this paper distributed storage systems with exact repair are studied. A construction for regenerating codes between the minimum storage regenerating (MSR) and the minimum bandwidth regenerating (MBR) points is given. To the best of author's knowledge,
