Symbol-Level Precoding for Minimizing Ranging CRB in ISAC Systems: A Low-Complexity Approach

This letter investigates a dual-functional waveform design for MIMO-OFDM integrated sensing and communication (ISAC) systems. Firstly, an optimization problem of minimizing the radar ranging Cramér-Rao bound (CRB) is formulated under the constraints of multi-user communication quality of service (QoS) and transmit powe...

MADRL-Based Multiobjective Joint Task Offloading and Resource Allocation in Heterogeneous IIoT

In Industrial Internet of Things systems, heterogeneous devices generate tasks with diversified quality-of-service (QoS), including latency-sensitive tasks and energy-sensitive tasks. However, most existing task offloading approaches optimize a single performance metric or convert multi-objective problem into weighted...

Understanding the Optimization Dynamics of Large Language Models: A Perspective from Non-Equilibrium Statistical Physics

The training process of modern deep learning models, particularly Large Language Models (LLMs), exhibits complex stochastic behaviors that are difficult to explain using traditional optimization theories. In this paper, we propose a novel perspective by modeling the optimization process of neural networks as a non-equi...

Movable Antenna Enabled RIS-Aided ISAC Systems With Self-Interference Suppression

In this paper, a movable antenna enabled reconfigurable intelligent surface (RIS)-aided ISAC system is investigated, where the monostatic BS attempts to detect a single target while providing communication services for multiple users by utilizing a RIS. To characterize the inherent performance trade-off between sensing...
