Abstract:The second part of this thesis addresses the problem of finding the capacity of two-dimensional (1, infinity) constrained channels for a binary alphabet. The Shannon capacity of a constrained channel is generalized to a notion of soft capacity which allows violations of the constraint. By drawing an analogy with an Ising array of the same geometry, it is proven that finding the soft capacity is equivalent to finding the partition function of the Ising model. Therefore, the problem of finding the capacity of a two-dimensional (1, infinity) constrained channel is reduced to the problem of finding an eigenvalue of a matrix.
