A system of error control for data transmission wherein the receiving device has the capability to detect and correct any character or code block that contains fewer than a predetermined number of symbols in error. Note: FEC is accomplished by adding bits to each transmitted character or code block, using a predetermined algorithm.

Sending redundant data so that if data loss occurs, data recovery is possible without retransmission

Adds unique codes to the digital signal at the source so errors can be detected and corrected at the receiver.

Forward error correction (FEC) is a digital signal processing technique used to enhance data reliability. It does this by introducing redundant data, called error correcting code, prior to data transm [..]

FEC is a method receiving stations or modems use to allows for the correction of transmission errors without the need to re-send the data.
