The Capacity of a Class of Channels
David Blackwell, Leo Breiman, Aram J. Thomasian · The Annals of Mathematical Statistics · 1959
Shannon's basic theorem on the capacity of a channel is generalized to the case of a class of memoryless channels. A generalized capacity is defined and is shown to be the supremum of attainable transmission rates when the coding and decoding procedure must be satisfactory for every channel in the class.
