Multihop Backhaul Compression for the Uplink of Cloud Radio Access Networks
Seok-Hwan Park, Osvaldo Simeone, Onur Sahin +1
In cloud radio access networks (C-RANs), the baseband processing of the radio units (RUs) is migrated to remote control units (CUs). This is made possible by a network of backhaul…
Performance Evaluation of Multiterminal Backhaul Compression for Cloud Radio Access Networks
Seok-Hwan Park, Osvaldo Simeone, Onur Sahin +1
In cloud radio access networks (C-RANs), the baseband processing of the available macro- or pico/femto-base stations (BSs) is migrated to control units, each of which manages a sub…
Multi-Layer Transmission and Hybrid Relaying for Relay Channels with Multiple Out-of-Band Relays
Seok-Hwan Park, Osvaldo Simeone, Onur Sahin +1
In this work, a relay channel is studied in which a source encoder communicates with a destination decoder through a number of out-of-band relays that are connected to the decoder…
Joint Precoding and Multivariate Backhaul Compression for the Downlink of Cloud Radio Access Networks
Seok-Hwan Park, Osvaldo Simeone, Onur Sahin +1
This work studies the joint design of precoding and backhaul compression strategies for the downlink of cloud radio access networks. In these systems, a central encoder is connecte…
Multi-Layer Hybrid-ARQ for an Out-of-Band Relay Channel
Seok-Hwan Park, Osvaldo Simeone, Onur Sahin +1
This paper addresses robust communication on a fading relay channel in which the relay is connected to the decoder via an out-of-band digital link of limited capacity. Both the sou…
