A Deterministic Algorithm for the Capacity of Finite-State Channels
Chengyu Wu, Guangyue Han, Venkat Anantharam +1
We propose two modified versions of the classical gradient ascent method to compute the capacity of finite-state channels with Markovian inputs. For the case that the channel mutua…
Improved Lower Bounds on Capacities of Symmetric 2-Dimensional Constraints using Rayleigh Quotients
Erez Louidor, Brian Marcus
A method for computing lower bounds on capacities of 2-dimensional constraints having a symmetric presentation in either the horizontal or the vertical direction is presented. The…
Asymptotics of Entropy Rate in Special Families of Hidden Markov Chains
Guangyue Han, Brian Marcus
We derive an asymptotic formula for entropy rate of a hidden Markov chain around a "weak Black Hole". We also discuss applications of the asymptotic formula to the asymptotic behav…
Derivatives of Entropy Rate in Special Families of Hidden Markov Chains
Guangyue Han, Brian Marcus
Consider a hidden Markov chain obtained as the observation process of an ordinary Markov chain corrupted by noise. Zuk, et. al. [13], [14] showed how, in principle, one can explici…
