So, information cannot be guaranteed to be transmitted reliably across a channel at rates beyond the channel capacity. In information theory, the noisy-channel coding theorem (sometimes Shannon's theorem), establishes that for any given degree of noise contamination of a communication channel, it is possible to communicate discrete data (digital Wolfowitz, J., "The coding of messages subject to chance errors", Illinois J.

That is, P r ( W = w ) = 2 − n R , w = 1 , 2 , … , 2 n R {\displaystyle Pr(W=w)=2^{-nR},w=1,2,\dots ,2^{nR}} . Copyright © 2016 ACM, Inc.

This result was presented by Claude Shannon in 1948 and was based in part on earlier work and ideas of Harry Nyquist and Ralph Hartley. The channel inclusion preorder includes the input-output degradation preorder, which can be found in [5], as a special case.

Even though the MMI decoder is no longer treated within this family of decoders with additive decision rules, the authors of [12] note that d-decoders still provide a broad enough framework

Namba Y. n R = H ( W ) = H ( W | Y n ) + I ( W ; Y n ) {\displaystyle nR=H(W)=H(W|Y^{n})+I(W;Y^{n})\;} using identities involving entropy and mutual We give equivalent characterizations in terms of $\chi^2$-divergence, L\"{o}wner (PSD) partial order, and spectral radius.

Shannon only gave an outline of the proof. For any pb, rates greater than R(pb) are not achievable.
