Optimization of User Selection and Bandwidth Allocation for Federated Learning in VLC/RF Systems
Optimization of User Selection and Bandwidth Allocation for Federated Learning in VLC/RF Systems
Limited radio frequency (RF) resources restrict the number of users that can participate in federated learning (FL) thus affecting FL convergence speed and performance. In this paper, we first introduce visible light communication (VLC) as a supplement to RF in FL and build a hybrid VLC/RF communication system, in which …
