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…
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…
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…
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…
