Covert Air–Ground Federated Learning With Pruning: Enabling by STAR-RIS

Federated learning (FL) can safeguard the data privacy for air-ground networks, while simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) can help further enhance its channel quality. However, the model exchanges in FL may be detected by wardens, and air-ground links increase this t...

Decentralized Cascaded Channel Estimation and Active User Detection for RIS-Assisted IoT Networks

Reconfigurable intelligent surface (RIS) is a promising technology for enhancing coverage and connectivity in Internet of Things (IoT) networks. However, the passive nature of RIS impedes the decoupling of the BS-RIS channel and RIS-user channels from the cascaded channel, making both channel estimation (CE) and active...
