Beschreibung

Later printing. 20 pages. 10 5/8 x 8 3/8 inches. Publisher's light blue and grey printed stapled wrappers. Five holes punched at the spine, as issued. Lightly worn with sun fading at the extremities and soiling to the lower-left corner. Wraps. "In this paper, we will develop certain extensions and refinements of coding theory for noisy communication channels. First, a refinement of the argument based on 'random' coding will be used to obtain an upper bound on the probability of error for an optimal code in the memoryless finite discrete channel. Next, an equation is obtained for the capacity of a finite state channel when the state can be calculated at both transmitting and receiving terminals. An analysis is also made of the more complex case where the state is calculable at the transmitting point but not necessarily at the receiving point" (abstract) "Information and Control," Vol 1 pp. 6-25, September 1957 first published this paper. An offprint from that journal is known. Here offered as a reprint from the Bell System Monograph series (#2982: June 1958). PROVENANCE: The personal files of Claude E. Shannon (unmarked). There were multiple examples of this item in Claude Shannon's files.

Slepian, editor, "Key Papers in the Development of Information Theory," IEEE Press, NY, 1974, pp 124-129 COLLECTORS NOTE: The Bell Telephone System Monograph series offered a way to obtain individual articles by Bell scientists regardless of where their work was first published. Many Monographs significantly postdate the original article publication. Because of this, they rarely constitute the coveted (and traditional) article offprint. If the journal of record issued no offprint, the Monograph might be the first separate publication - the closest the collector can come to a traditional offprint. We have done our best to place each Monograph properly in the article's publishing history and welcome any corrections or additional information, especially regarding issues unknown to us.
