Recently, an intriguing 2D metamaterial, called the metasurface,[24] has gained attention
due to its ability to manipulate optical phase fronts. Instead of acquiring a desired phase …

Building on the recent coded-caching breakthrough by Maddah-Ali and Niesen, the work
here considers the K-user cache-aided wireless multi-antenna symmetric broadcast channel …

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. It is assumed that …

An erasure broadcast network is considered with two disjoint sets of receivers: a set of weak
receivers with all-equal erasure probabilities and equal cache sizes and a set of strong …

This paper aims to provide an optimization framework for coded caching that accounts for
various heterogeneous aspects of practical systems. An optimization theoretic perspective …

We consider the coded caching problem with a central server containing N files, each of
length F bits, and K users, each equipped with a cache of capacity MF bits. We assume that …

Decentralized proactive caching and coded delivery is studied in a content delivery network,
where each user is equipped with a cache memory, not necessarily of equal capacity …

Degraded K-user broadcast channels (BCs) are studied when the receivers are facilitated
with cache memories. Lower and upper bounds are derived on the capacity-memory …

Improved lower bounds are derived on the average and worst case rate-memory tradeoffs of
the Maddah-Ali and Niesen-coded caching scenario. For any number of users and files and …

A cache-aided broadcast network is studied, in which a server delivers contents to a group
of receivers over a packet erasure broadcast channel. The receivers are divided into two …
