Algorithms for -ary Error-Correcting Codes with Limited Magnitude and Feedback
Christian Deppe, Vladimir Lebedev
Berlekamp and Zigangirov completely determined the capacity error function for binary error correcting codes with noiseless feedback. It is still an unsolved problem if the upper b…
Quantum Broadcast Channels with Cooperating Decoders: An Information-Theoretic Perspective on Quantum Repeaters
Uzi Pereg, Christian Deppe, Holger Boche
Communication over a quantum broadcast channel with cooperation between the receivers is considered. The first form of cooperation addressed is classical conferencing, where Receiv…
Secure Identification for Gaussian Channels and Identification for Multi-Antenna Gaussian Channels
Wafa Labidi, Christian Deppe, Holger Boche
New applications in modern communications are demanding robust and ultra-reliable low latency information exchange such as machine-to-machine and human-to-machine communications. F…
Optimal Signal Processing for Common Randomness Generation over MIMO Gaussian Channels with Applications in Identification
Rami Ezzine, Wafa Labidi, Christian Deppe +1
Common randomness (CR), as a resource, is not commonly exploited in existing practical communication systems. In the CR generation framework, both the sender and receiver aim to ge…
Deterministic Identification Over Fading Channels
Mohammad J. Salariseddigh, Uzi Pereg, Holger Boche +1
Deterministic identification (DI) is addressed for Gaussian channels with fast and slow fading, where channel side information is available at the decoder. In particular, it is est…
On Effective Convergence in Fekete's Lemma and Related Combinatorial Problems in Information Theory
Holger Boche, Yannik Böck, Christian Deppe
Fekete's lemma is a well known result from combinatorial mathematics that shows the existence of a limit value related to super- and subadditive sequences of real numbers. In this…
Computability of the Zero-Error Capacity of Noisy Channels
Holger Boche, Christian Deppe
Zero-error capacity plays an important role in a whole range of operational tasks, in addition to the fact that it is necessary for practical applications. Due to the importance of…
Deterministic Identification Over Channels With Power Constraints
Mohammad J. Salariseddigh, Uzi Pereg, Holger Boche +1
The identification capacity is developed without randomization at neither the encoder nor the decoder. In particular, full characterization is established for the deterministic ide…
How to apply the rubber method for channels with feedback
Christian Deppe, Vladimir Lebedev, Georg Maringer
We give an overview of applications of the rubber method. The rubber method is a coding algorithm that was developed in 2005 by Ahlswede, Deppe and Lebedev for channels with feedba…
Performance Analysis of Identification Codes
Sencer Derebeyoglu, Christian Deppe, Roberto Ferrara
In this paper we analyse the construction of identification codes. Identification codes are based on the question "Is the message I have just received the one I am interested in?",…
Coding with Noiseless Feedback over the Z-channel
Christian Deppe, Vladimir Lebedev, Georg Maringer +1
In this paper, we consider encoding strategies for the Z-channel with noiseless feedback. We analyze the combinatorial setting where the maximum number of errors inflicted by an ad…
Quantum Channel State Masking
Uzi Pereg, Christian Deppe, Holger Boche
Communication over a quantum channel that depends on a quantum state is considered when the encoder has channel side information (CSI) and is required to mask information on the qu…
Computability of the Zero-Error capacity with Kolmogorov Oracle
Holger Boche, Christian Deppe
The zero-error capacity of a discrete classical channel was first defined by Shannon as the least upper bound of rates for which one transmits information with zero probability of…
Bounds for the capacity error function for unidirectional channels with noiseless feedback
Christian Deppe, Vladimir Lebedev, Georg Maringer
In digital systems such as fiber optical communications, the ratio between probability of errors of type and can be large. Practically, one can assume that only…
Semantic Security for Quantum Wiretap Channels
Holger Boche, Minglai Cai, Christian Deppe +2
We consider the problem of semantic security via classical-quantum and quantum wiretap channels and use explicit constructions to transform a non-secure code into a semantically se…
