Litter-Masked Block z-Channel: Designing Cover Distributions Against Public-Design Observers
Bin Han, Wenwen Chen, Yao Zhu +3
Networking defenses against traffic analysis fill idle slots with cover traffic, yet the physical layer carrying it still hands upper layers the erasure-only model of a silent-idle…
Block Erasure Channel and Block z-Channel with Bounded Decoders and Finite Blocklength
Bin Han, Yao Zhu, Rafael F. Schaefer +5
Block error rate is a standard metric in finite blocklength (FBL) communication, yet it conflates two qualitatively different failure modes: block confusions, where the decoder sel…
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…
Finite Blocklength Performance of Capacity-achieving Codes in the Light of Complexity Theory
Holger Boche, Andrea Grigorescu, Rafael F. Schaefer +1
Since the work of Polyanskiy, Poor and Verdú on the finite blocklength performance of capacity-achieving codes for discrete memoryless channels, many papers have attempted to find…
Building Resilience in Wireless Communication Systems With a Secret-Key Budget
Karl-Ludwig Besser, Rafael F. Schaefer, H. Vincent Poor
Resilience and power consumption are two important performance metrics for many modern communication systems, and it is therefore important to define, analyze, and optimize them. I…
