Capacity and decoding rules for classes of arbitrarily varying channels

Ahstrucf -We consider the capacity of an arbitrarily varying channel (AVC) for deterministic codes with the average probability of error critenon and, typically, subject to a state constraint. First, sufficient conditions are provided that enable (relatively) simple decoding rules such as typicality, maximum mutual information, and minimum distance, to attain capacity. Then the (possibly noisy)...

Capacity Results for Arbitrarily Varying Wiretap Channels

In this work the arbitrarily varying wiretap channel AVWC is studied. We derive a lower bound on the random code secrecy capacity for the average error criterion and the strong secrecy criterion in the case of a best channel to the eavesdropper by using Ahlswede’s robustification technique for ordinary AVCs. We show that in the case of a non-symmetrisable channel to the legitimate receiver the ...

Correlated Decoding for Channels with Arbitrarily Varying Channel Probability Functions

Let X = I1, " '" , a}, Y = {1, ' " , b} be finite sets. A stochastic matrix w with a rows and b columns will be called a channel. X, Y are the input and output alphabets (respectively) of the channel. We denote the set of all channels with input alphabet X and output alphabet Y by e (X, Y). A channel w E C (X, Y) can be used for communication from one person, the sender, to another person, the ...

Gaussian arbitrarily varying channels

The arbitrarily varying channel (AVC) can be interpreted as a model of a channel jammed by an intelligent and unpredictable adversary. We investigate the asymptotic reliability of optimal random block codes on Gaussian arbitrarily varying channels (GAVC’s). A GAVC is a discrete-time memoryless Gaussian channel with input power constraint PT and noise power N,, which is further corrupted by an a...

Quantum capacity under adversarial quantum noise: arbitrarily varying quantum channels

We investigate entanglement transmission over an unknown channel in the presence of a third party (called the adversary), which is enabled to choose the channel from a given set of memoryless but non-stationary channels without informing the legitimate sender and receiver about the particular choice that he made. This channel model is called arbitrarily varying quantum channel (AVQC). We derive...
