Forward Error Correction

Forward Error Correction (FEC) is a technique used in communication systems to improve data integrity. It works by adding extra, redundant information to the original message before transmission. This allows the receiver to detect and correct certain errors without needing to ask for retransmission. FEC is especially useful in situations where resend is costly or impossible, such as streaming videos or satellite communications. By proactively correcting errors, FEC helps ensure that the received data matches the sent data accurately, leading to more reliable and efficient communication.
