A Mathematical Theory of Communication is an article by mathematician Claude E. Shannon published in Bell System Technical Journal in 1948.[1][2][3][4] It was renamed The Mathematical Theory of Communication in the 1949 book of the same name,[5] a small but significant title change after realizing the generality of this work.
Publication
Shannon's diagram of a general communications system, showing the process by which a message sent becomes the message received (possibly corrupted by noise).
The article was the founding work of the field of information theory. It was later published in 1949 as a book titled The Mathematical Theory of Communication (ISBN 0-252-72546-8), which was published as a paperback in 1963 (ISBN 0-252-72548-4). The book contains an additional article by Warren Weaver, providing an overview of the theory for a more general audience.
Contents
Shannon's article laid out the basic elements of communication:
An information source that produces a message
A transmitter that operates on the message to create a signal which can be sent through a channel
A channel, which is the medium over which the signal, carrying the information that composes the message, is sent
A receiver, which transforms the signal back into the message intended for delivery
A destination, which can be a person or a machine, for whom or which the message is intended
It also developed the concepts of information entropy and redundancy, and introduced the term bit (which Shannon credited to John Tukey) as a unit of information. It was also in this paper that the Shannon–Fano coding technique was proposed – a technique developed in conjunction with Robert Fano.
