Secrecy Capacity of a Gaussian Wiretap Channel With ADCs is Always Positive
Seung-Hyun Nam, Si-Hyeon Lee
We consider a complex Gaussian wiretap channel with finite-resolution analog-to-digital converters (ADCs) at both the legitimate receiver and the eavesdropper. For this channel, we…

Mobility-Assisted Covert Communication over Wireless Ad Hoc Networks
Hyeon-Seong Im, Si-Hyeon Lee
We study the effect of node mobility on the throughput scaling of the covert communication over a wireless adhoc network. It is assumed that mobile nodes want to communicate ea…

Treating Interference as Noise is Optimal for Covert Communication over Interference Channels
Kang-Hee Cho, Si-Hyeon Lee
We study the covert communication over K-user discrete memoryless interference channels (DM-ICs) with a warden. It is assumed that the warden's channel output distribution induced…
