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…
