forward error correction

[′fȯr·wərd ′er·ər kə‚rek·shən]
(communications)

Forward Error Correction

(algorithm)
(FEC) A class of methods for controling errors in a one-way communication system. FEC sends extra information along with the data, which can be used by the receiver to check and correct the data.

A CPU writing data to RAM is a kind of one-way communication - see error correcting memory and error checking and correction.

forward error correction

The primary method for detecting and correcting errors in transmitted data. Forward error correction (FEC) adds bits to the outgoing message, and the receiving end uses those bits to detect and correct errors. See channel coding.

Error-correcting codes are types of error control coding techniques that are used a noisy communication channel to detect and correct errors at the receiving end in case of forward error correction, they have been described by Bruen and Forcinito, 2011; Huffman and Pless, 2003; Peterson and Weldon, 1972, [7, 19, 20].
