We consider a basic caching system, where a single server with a database of N files (eg,
movies) is connected to a set of K users through a shared bottleneck link. Each user has a …

In the context of coded caching in the K-user broadcast channel, our work reveals the
surprising fact that having multiple (L) transmitting antennas, dramatically ameliorates the …

Caching is an efficient way to reduce network traffic congestion during peak hours, by
storing some content at the user's local cache memory, even without knowledge of user's …

The centralized coded caching scheme is a technique proposed by Maddah-Ali and Niesen
as a method to reduce the network burden in peak times in a wireless network system. Yan …

We consider the problem of private information retrieval (PIR) from N non-colluding and
replicated databases when the user is equipped with a cache that holds an uncoded fraction …

The work explores the fundamental limits of coded caching in the setting where a transmitter
with potentially multiple (N 0) antennas serves different users that are assisted by a smaller …

We investigate the potentials of applying the coded caching paradigm in wireless networks.
In order to do this, we investigate physical layer schemes for downlink transmission from a …

The rank metric measures the distance between two matrices by the rank of their difference.
Codes designed for the rank metric have attracted considerable attention in recent years …

We propose a new coded caching scheme where linear combinations of the file segments
are cached at the users, for the cases where the number of files is no greater than the …

Caching is an efficient way to reduce network traffic congestion during peak hours by storing
some content at the user's local cache memory without knowledge of later demands. For the …
