Forward Error Correction. An error control mode in which a detected error triggers an automatic error correction process in the receiver. FEC involves adherence to a set of specific rules of data construction and the addition of sufficient redundant data in order that the receiving device can identify, isolate, and correct a certain number (depending on the method) of errors without requiring retransmission. FEC often is used in networks where link quality is poor and bandwidth is limited, or where latency is high. FEC is used, for example, in cellular and other wireless networks in support of e-mail, short message service (SMS), and Internet access. Two commonly employed techniques are Hamming code and BCH (Bose, Chaudhuri, and Hocquengham). FEC also is used extensively in satellite communications. See also 1/3 FEC, BCH, error control, Hamming code, recognition and flagging, and recognition and retransmission.
