Confusions and Erasures of Error-Bounded Block Decoders with Finite Blocklength
Bin Han, Yao Zhu, Rafael F. Schaefer +4
This paper investigates two distinct types of block errors - undetected errors (confusions) and erasures - in additive white Gaussian noise (AWGN) channels with error-bounded block…
Characterization of the Arithmetic Complexity of the Secrecy Capacity of Fast-Fading Gaussian Channels
Holger Boche, Andrea Grigorescu, Rafael F. Schaefer +1
This paper studies the computability of the secrecy capacity of fast-fading wiretap channels from an algorithmic perspective, examining whether it can be computed algorithmically o…
On the Need of Neuromorphic Twins to Detect Denial-of-Service Attacks on Communication Networks
Holger Boche, Rafael F. Schaefer, H. Vincent Poor +1
As we are more and more dependent on the communication technologies, resilience against any attacks on communication networks is important to guarantee the digital sovereignty of o…
How Should IRSs Scale to Harden Multi-Antenna Channels?
Ali Bereyhi, Saba Asaad, Chongjun Ouyang +3
This work extends the concept of channel hardening to multi-antenna systems that are aided by intelligent reflecting surfaces (IRSs). For fading links between a multi-antenna trans…
Channel Hardening of IRS-Aided Multi-Antenna Systems: How Should IRSs Scale?
Ali Bereyhi, Saba Asaad, Chongjun Ouyang +3
Unlike active array antennas, intelligent reflecting surfaces (IRSs) are efficiently implemented at large dimensions. This allows for traceable realizations of large-scale IRS-aide…
Capacity of Finite State Channels with Feedback: Algorithmic and Optimization Theoretic Properties
Andrea Grigorescu, Holger Boche, Rafael F. Schaefer +1
The capacity of finite state channels (FSCs) with feedback has been shown to be a limit of a sequence of multi-letter expressions. Despite many efforts, a closed-form single-letter…
