Wireless Federated Learning over MIMO Networks: Joint Device Scheduling and Beamforming Design

no code implementations31 Oct 2021 Shaoming Huang, Pengfei Zhang, Yijie Mao, Lixiang Lian, Yuanming Shi

Specifically, we theoretically establish the convergence analysis of the FL process, and then apply the proposed device scheduling policy to maximize the number of weighted devices under the FL system latency and sum power constraints.
