Forward Error Correction

(algorithm)(FEC) A class of methods for controling errors ina one-way communication system. FEC sends extra informationalong with the data, which can be used by the receiver tocheck and correct the data.

A CPU writing data to RAM is a kind of one-waycommunication - see error correcting memory and error checking and correction.

forward error correction
