On the Capacity of Generalized Ising Channels

2017 IEEE Transactions on Information Theory  
Nearly tight lower and upper bounds on the capacity of generalized Ising channels are presented. For the case where feedback is allowed, a closed-form expression for the capacity is found for channel error probability p ∈ [0, p0], where p0 ≈ 0.398324. Two lower bounds on that capacity for larger values of p are presented.
