DOI: 10.1109/tgcn.2025.3545925
Abstract: Full-duplex (FD) systems enable users to simultaneously transmit and receive information on the same frequency, theoretically enhancing spectrum efficiency. However, the inherent openness and broadcasting nature of wireless communication pose significant security risks, especially in… read more here.
