講座內(nèi)容：This talk deals with the fundamental performance study of physical layer security in wireless networks. I will first discuss the secrecy performance of correlated fading wire-tap channel, and then introduce some of our recent works on secrecy transmission capacity analysis of noisy wireless ad hoc networks under the non-cooperative jamming technique. Finally, I talk about the eavesdropper-tolerance capacity study of two-hop wireless networks under the cooperative jamming technique.
