Single-RF Multi-User Communication Through Reconfigurable Intelligent Surfaces: An Information-Theoretic Analysis
Roy Karasik, Osvaldo Simeone, Marco Di Renzo +1
Reconfigurable intelligent surfaces (RISs) are typically used in multi-user systems to mitigate interference among active transmitters. In contrast, this paper studies a setting wi…
Adaptive Coding and Channel Shaping Through Reconfigurable Intelligent Surfaces: An Information-Theoretic Analysis
Roy Karasik, Osvaldo Simeone, Marco Di Renzo +1
A communication link aided by a reconfigurable intelligent surface (RIS) is studied in which the transmitter can control the state of the RIS via a finite-rate control link. Channe…
Information-Theoretic Analysis of D2D-Aided Pipelined Content Delivery in Fog-RAN
Roy Karasik, Osvaldo Simeone, Shlomo Shamai
In a Fog-Radio Access Network (F-RAN), edge caching and fronthaul connectivity to a cloud processor are utilized for the purpose of content delivery. Additional Device-to-Device (D…
Beyond Max-SNR: Joint Encoding for Reconfigurable Intelligent Surfaces
Roy Karasik, Osvaldo Simeone, Marco Di Renzo +1
A communication link aided by a Reconfigurable Intelligent Surface (RIS) is studied, in which the transmitter can control the state of the RIS via a finite-rate control link. Prior…
How Much Can D2D Communication Reduce Content Delivery Latency in Fog Networks with Edge Caching?
Roy Karasik, Osvaldo Simeone, Shlomo Shamai
A Fog-Radio Access Network (F-RAN) is studied in which cache-enabled Edge Nodes (ENs) with dedicated fronthaul connections to the cloud aim at delivering contents to mobile users.…
Robust Uplink Communications over Fading Channels with Variable Backhaul Connectivity
Roy Karasik, Osvaldo Simeone, Shlomo Shamai
Two mobile users communicate with a central decoder via two base stations. Communication between the mobile users and the base stations takes place over a Gaussian interference cha…
