forward error correction

[′fȯr·wərd ′er·ər kə‚rek·shən]
The location and correction of errors occurring in data communications by the receiver without retransmission of data.

Forward Error Correction

(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

A communications technique that can correct bad data on the receiving end. Before transmission, the data are processed through an algorithm that adds extra bits for error correction. If the transmitted message is received in error, the correction bits are used to repair it.
