In this paper, we address the challenging issue of multi-hop cooperative relaying over heterogeneous compound channels, where constituent channels can incorporate topographical variations and respective distribution changes (due to environmental factors). Existing methods in the literature address various issues pertinent to receiver design by assuming a homogeneous framework. Since real-time s...

To expedite research progress on terahertz (THz) communications, we analyze the outage performance of THz communication systems by a compound channel model in this paper. Different from existing models, incorporates effects spreading loss, molecular absorption shadowing, and multi-path fading via composite distribution. By using model, maintain an equilibrium analysis between mathematical tract...

We analyze physical-layer security based on the premise that the coding mechanism for secrecy over noisy channels is tied to the notion of resolvability. Instead of considering capacity-based constructions, which associate to each message a sub-code that operates just below the capacity of the eavesdropper’s channel, we consider resolvability-based constructions, which associate to each message...
