The zero error capacity of a noisy channel

Shannon, C.·1956·IEEE Transactions on Information Theory

Abstract

The zero error capacityC_oof a noisy channel is defined as the least upper bound of rates at which it is possible to transmit information with zero probability of error. Various properties ofC_oare studied; upper and lower bounds and methods of evaluation ofC_oare given. Inequalities are obtained for theC_orelating to the "sum" and "product" of two given channels. The analogous problem of zero error capacityC_oFfor a channel with a feedback link is considered. It is shown that while the ordinary capacity of a memoryless channel with feedback is equal to that of the same channel without feedback, the zero error capacity may be greater. A solution is given to the problem of evaluatingC_oF.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
