abstract = "In this work, we study differential privacy (DP) for federated learning over multiple antenna wireless communications. Specifically, we revisit DP from the perspective of wireless communications and propose an efficient beamforming scheme that can reduce inevitable degradation of inference accuracy due to intentional noises from DP. We also propose a power allocation scheme guaranteeing DP for the proposed beamforming scheme. Simulation results demonstrate that the proposed scheme can effectively prevent inference accuracy loss caused by DP."
