Penalty-Free GNN Framework for Joint Optimization in RIS-Assisted ISAC Systems

Jointly optimizing base station beamforming and reconfigurable intelligent surface (RIS) phase shifts in integrated sensing and communication (ISAC) systems under strict sensing constraints presents a challenging non-convex problem. Conventional algorithms suffer from high complexity, while penalty-based deep learning...
