Streamlined Swift Allocation Strategies for Sequential Fronthaul Cell-Free Massive MIMO

IEEE Access
Centralized access point (AP) selection approaches in sequential fronthaul cell-free (SF-CF) networks, such as centralized maximum ratio combining (CMRC) or centralized optimal sequence linear processing (COSLP), often hinder its scalability by ...

Task-Oriented Edge Networks: Decentralized Learning Over Wireless Fronthaul

IEEE Internet of Things Journal
This paper studies task-oriented edge networks where multiple edge internet-of-things nodes execute machine learning tasks with the help of powerful deep neural networks (DNNs) at a network cloud. Separate edge nodes (ENs) result in a partially observable system where they can only get partitioned features of the global network states.

Enhanced Fronthaul Capacity in CRANs: Sum-Rate Maximization via Joint Optimal Design of STAR-RIS, Massive MIMO and Data Compression

IEEE Open Journal of Vehicular Technology
Cloud Radio Access Networks (CRAN) face a critical challenge due to the limited capacity of fronthaul links overwhelmed by massive data transmissions. This paper proposes a novel CRAN design that effectively tackles this challenge.
