Joint Optical and Wireless Resource Allocation for Cooperative Transmission in C-RAN

Sensors, 2020
Cooperative multipoint transmission (CoMP) is one of the most promising paradigms for mitigating interference in cloud radio access networks (C-RAN). It allows multiple remote radio units (RRUs) to transmit the same data flow to a user to further improve

Performance of Cell-Free Massive MIMO With Joint User Clustering and Access Point Selection

IEEE Access, 2021
We consider an uplink cell-free massive multiple-input multiple-output (MIMO) system, in which the access points are connected to the central processing unit (CPU) through a fronthaul network.
