Asymptotically, this error correcting capability meets the famous Gilbert—Varshamov bound. Please help us clarify the article.

This article may be confusing or coses to readers. Riemann—Roch theorem for more. Note that in binary case, locating the errors is sufficient to correct them, as there’s only one other value possible. Retrieved from ” https: Views Read Edit View history.

In particular cases, they can have interesting extremal properties. They should not be confused with Binary Goppa codes that are used, for instance, in the McEliece cryptosystem.

The vector space is a subspace of the function field of X. Please help improve it or discuss these issues on the talk page.

Such codes were introduced by Valerii Denisovich Goppa. In non-binary cases a separate error correction polynomial has to be computed as well.

Because of the high error correction capacity compared to code rate and form of parity-check matrix which is usually hardly distinguishable from a random binary matrix of full rankthe binary Goppa codes are used in several post-quantum cryptosystemsnotably McEliece cryptosystem and Niederreiter cryptosystem. From Dodes, the free encyclopedia.
