FEC: Forward Error Correction
Forward Error Correction (FEC) is a technique for controlling 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. Using FEC, a receiver can correct errors incurred in transmission over a communications channel without requiring retransmission of any information by the transmitter, which typically involves a convolution of the transmitted bits and the appending of extra bits by both the receiver and transmitter using a common algorithm.
