Optimal Number of Transmit Antennas for Secrecy Enhancement in Massive MIMOME Channels
Saba Asaad, Ali Bereyhi, Ralf R. Müller +2
This paper studies the impact of transmit antenna selection on the secrecy performance of massive MIMO wiretap channels. We consider a scenario in which a multi-antenna transmitter…
Wiretap Channels: Nonasymptotic Fundamental Limits
Wei Yang, Rafael F. Schaefer, H. Vincent Poor
This paper investigates the maximal secret communication rate over a wiretap channel subject to reliability and secrecy constraints at a given blocklength. New achievability and co…
Improper Signaling for Virtual Full-Duplex Relay Systems
Mohamed Gaafar, Osama Amin, Rafael F. Schaefer +1
Virtual full-duplex (VFD) is a powerful solution to compensate the rate loss of half-duplex relaying without the need to full-duplex capable nodes. Inter-relay interference (IRI) c…
On MMSE Properties of Codes for the Gaussian Broadcast and Wiretap Channels
Ronit Bustin, Rafael F. Schaefer, H. Vincent Poor +1
This work concerns the behavior of "good" (capacity achieving) codes in several multi-user settings in the Gaussian regime, in terms of their minimum mean-square error (MMSE) behav…
