Abstract :
List-decoding for arbitrarily varying channels (AVCs) under state constraints is investigated. It is shown that rates within ϵ of the randomized coding capacity of AVCs with input-dependent state can be achieved under maximal error with list-decoding using lists of size O(1/ϵ). Under the average error criterion, an achievable rate and converse bound are given for lists of size L . These bounds are based on two different notions of symmetrizability and do not coincide in general. An example is given which shows that for list size L , the capacity may be positive but strictly smaller than the randomized coding capacity, in contrast to the situation without constraints.
