What happened
Collection of recent arXiv papers (communications, signal processing, coding theory) focused on metasurfaces/RIS, large-scale discrete optimization, coding and algebraic results, covert and task-oriented communications, integrated sensing and communication (ISAC), near-field/XL-MIMO channel estimation, and efficient finite-field arithmetic. Security-relevant points: (1) two papers address covert communication and finite-blocklength covert rates (privacy/stealth communications implications); (2) advances in RIS/FIM design and scalable discrete phase optimization (including a physical CIM solver
