Forward error correction
In
telecommunication, a
forward error correction (FEC) is 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.
