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…
Throughput Scaling of Covert Communication over Wireless Adhoc Networks
Kang-Hee Cho, Si-Hyeon Lee, Vincent Y. F. Tan
We consider the problem of covert communication over wireless adhoc networks in which (roughly) legitimate nodes (LNs) and for non-communicating warden nodes (WNs…
Covert Communication with Channel-State Information at the Transmitter
Si-Hyeon Lee, Ligong Wang, Ashish Khisti +1
We consider the problem of covert communication over a state-dependent channel, where the transmitter has causal or noncausal knowledge of the channel states. Here, "covert" means…
The Wiretapped Diamond-Relay Channel
Si-Hyeon Lee, Ashish Khisti
In this paper, we study a diamond-relay channel where the source is connected to relays through orthogonal links and the relays transmit to the destination over a wireless mult…
