Improper Signaling in Two-Path Relay Channels
Mohamed Gaafar, Osama Amin, Rafael F. Schaefer +1
Inter-relay interference (IRI) challenges the operation of two-path relaying systems. Furthermore, the unavailability of the channel state information (CSI) at the source and the l…
Secret Key Generation Through a Relay
Kittipong Kittichokechai, Rafael F. Schaefer, Giuseppe Caire
We consider problems of two-user secret key generation through an intermediate relay. Each user observes correlated source sequences and communicates to the relay over rate-limited…
Secret-Key Generation Using Compound Sources and One-Way Public Communication
Nima Tavangaran, Holger Boche, Rafael F. Schaefer
In the classical Secret-Key generation model, Common Randomness is generated by two terminals based on the observation of correlated components of a common source, while keeping it…
Finite-Blocklength Bounds for Wiretap Channels
Wei Yang, Rafael F. Schaefer, H. Vincent Poor
This paper investigates the maximal secrecy rate over a wiretap channel subject to reliability and secrecy constraints at a given blocklength. New achievability and converse bounds…
