Joint Energy and Latency Optimization in Federated Learning over Cell-Free Massive MIMO Networks

no code implementations28 Apr 2024 Afsaneh Mahmoudi, Mahmoud Zaher, Emil Björnson

Federated learning (FL) is a distributed learning paradigm wherein users exchange FL models with a server instead of raw datasets, thereby preserving data privacy and reducing communication overhead.

Soft Handover Procedures in mmWave Cell-Free Massive MIMO Networks

no code implementations6 Sep 2022 Mahmoud Zaher, Emil Björnson, Marina Petrova

The algorithms provide a systematic procedure for initial access and update of the serving APs and assigned pilot sequence to each UE.

Learning-Based Downlink Power Allocation in Cell-Free Massive MIMO Systems

1 code implementation7 Sep 2021 Mahmoud Zaher, Özlem Tuğfe Demir, Emil Björnson, Marina Petrova

Further, we develop a clustered DNN model where the LSF parameters of a small number of APs, forming a cluster within a relatively large network, are used to jointly approximate the power coefficients of the cluster.
