Information on Forward Error Correction (FEC)

Using forward error correction the receiver is able to correct errors itself without reference to the transmitter. It does this by using additional information transmitted along with the data and employing one of the error detection techniques. The receiver can correct a small number of the errors that have been detected. If the receiver cannot correct all detected errors, the data must be re-transmitted.
