Definitions for "Forward Error Correction"
Technique for regenerating lost data transmissions or error messages; retransmission of any information by the transmitter. [Typically, this is accomplished by adding bits to each transmitted character or code clock using a predetermined algorithm. It doesn't need a feedback channel, and therefore may be used with a one-way transmission system.
The purpose of this element is to add unique codes to the digital signal at the output source so problems can be detected at the signal receiver.
FEC is a technique for improving the accuracy of data transmission. Excess bits are included in the outgoing data stream so that error correction algorithms can be applied upon reception.
Increases voice quality by recovering lost or corrupted packets.
