Title: HOLOGRAPHIC RADIO: A NEW PARADIGM FOR ULTRA-MASSIVE MIMO
Abstract: Ultra-massive multiple-input multiple-output (MIMO) is one of the key enablers in the forthcoming sixth generation (6G) networks to provide revolutionary mobile connectivity and high-speed data services by exploiting spatial diversity. Widely-utilized phased arrays relying on costly components make the implementation of ultra-massive MIMO in practice become prohibitive from both cost and power consumption perspectives. The recent developed reconfigurable holographic surfaces (RHSs) composing of densely packing sub-wavelength metamaterial elements can achieve holographic beamforming without costly hardware components. By leveraging the holographic principle, the RHS serves as an ultra-thin and lightweight surface antenna integrated with the transceiver, thereby providing a promising alternative to phased arrays for realizing ultra-massive MIMO. In this tutorial, we will first provide a basic introduction of RHSs. We then introduce the unique features of RHSs which enables both communication and sensing, in a comprehensive way. Related design, analysis, optimization, and signal processing techniques will be presented. Typical RHS-based applications for the wireless communications and radio-frequency sensing will be explored. The implementation issues along with our developed prototypes and experiments will also be discussed. Several up-to-date challenges and potential research directions will be discussed as well.

Title: Optimizing Federated Learning: A Novel DP-FedSAdam Algorithm for Enhanced Privacy and Performance
Abstract: Federated learning allows multiple parties to collaborate on training shared models in a privacy-preserving manner. But FL involves frequent communication between the server and the participant, which can compromise the privacy of the client. To address this, client-level differential privacy federated learning (DPFL) introduces locally updated clips and noise additions to improve privacy. However, this increased noise can degrade the performance of the model. In this study, we propose an optimization algorithm using SAM+ADAM optimizer, which aims to reduce the noise impact and the number of communication rounds to improve resource efficiency. The DP-FedSAdam proposed in this paper, combined with sharpness-perceptual minimization, creates a model with improved stability and resistance to weight perturbations, minimizing local update specifications and enhancing resilience to DP noise. As a result, it achieves optimal model parameters and reduced resource usage. A large number of experiments and comparative analyses verify the superiority of the proposed algorithm compared with traditional methods.
