A technique used by a receiver for correcting errors incurred in transmission over a communications channel without requiring retransmission of any information by the transmitter; typically involves a convolution of the transmitted bits and the appending of extra bits by both the receiver and transmitter using a common algorithm.
A technique for correcting errors incurred in transmission over a communications channel. With FEC, errors are corrected at the receiving end of the channel, thereby reducing the amount of data that must be retransmitted due to errors.
Foward Error Correction. A class of methods for controling errors in a communication system. FEC sends extra information along with the data, which can be used by the receiver to check and correct the data. Examples of Foward Error Correction algorithms are Reed Solomon, Viterbi and Turbo Product Coding
