For the second type of coopera- tive jamming, although CSI is not required to share, jamming impairs the legitimate channels and then limits the secrecy.
In order to improve security, we propose a novel cooperative jamming scheme, in which users do not share channel state information (CSI) but the legitimate ...
We investigate the secure degrees of freedom (s.d.o.f.) of three new channel models: broadcast channel with combating helpers, interference channel with ...
Oct 22, 2024 · To address this problem, we propose a cross-time interference injection scheme in this paper, which improves security by introducing cross-time ...
