Squeezing the Arimoto-Blahut algorithm for faster convergence

Published 21 Jun 2009 in cs.IT, math.IT, and stat.CO | (0906.3849v1)

Abstract: The Arimoto--Blahut algorithm for computing the capacity of a discrete memoryless channel is revisited. A so-called ``squeezing'' strategy is used to design algorithms that preserve its simplicity and monotonic convergence properties, but have provably better rates of convergence.
