• Forward error correction — In telecommunication, information theory, and coding theory, forward error correction (FEC) or channel coding[1] is a technique used for controlling errors in data transmission over unreliable or noisy communication channels. The central idea is… …   Wikipedia

• Forward Error Correction — Vorwärtsfehlerkorrektur (kurz FEC von engl. forward error correction, manchmal auch EDAC, für engl. error detection and correction) ist eine Technik, die dazu dient, die Fehlerrate bei der Speicherung oder der Übertragung digitaler Daten zu… …   Deutsch Wikipedia

• Forward Error Correction — En télécommunications, FEC (pour Forward Error Correction) est un système de protection contre les erreurs utilisé lors de la transmission de données. L émetteur ajoute de la redondance afin de permettre au destinataire de détecter et de corriger …   Wikipédia en Français

• forward error correction —    A technique used to control errors that insert extra or redundant bits into the data stream. The receiving device uses the redundant bits to detect and, if possible, correct the errors in the data.    See also error detection and correction …   Dictionary of networking

• forward error correction —    Data transmission where redundant bits produced at the transmitted end are used at the receiving terminal to detect, locate and correct any errors before delivery to the local data communications link …   IT glossary of terms, acronyms and abbreviations

• Reed–Solomon error correction — Reed Solomon error correction is an error correcting code that works by oversampling a polynomial constructed from the data. The polynomial is evaluated at several points, and these values are sent or recorded. Sampling the polynomial more often… …   Wikipedia

• Error detection and correction — In mathematics, computer science, telecommunication, and information theory, error detection and correction has great practical importance in maintaining data (information) integrity across noisy channels and less than reliable storage… …   Wikipedia

• error detection and correction —    A mechanism used to determine whether transmission errors have occurred and, if so, to correct those errors.    Some programs or transmission protocols simply request a retransmission of the affected block of data if an error is detected.

• Soft error — In electronics and computing, an error is a signal or datum which is wrong. Errors may be caused by a defect, usually understood either to be a mistake in design or construction, or a broken component. A soft error is also a signal or datum which …   Wikipedia

• Feed-forward — is a term describing a kind of system which reacts to changes in its environment, usually to maintain some desired state of the system. A system which exhibits feed forward behavior responds to a measured disturbance in a pre defined way mdash;… …   Wikipedia
