Forward Error Correction
Forward Error Correction (FEC) is a technique used in space and astronautical engineering to improve the reliability of data transmission over noisy or unreliable communication channels. FEC adds redundant information to the transmitted data, allowing the receiver to detect and correct errors without the need for retransmission. This technique is particularly useful in space missions where retransmission is not possible due to the long distances involved. FEC can be implemented using various codes such as Reed-Solomon, Turbo, and Low-Density Parity-Check (LDPC) codes. The choice of code depends on the specific requirements of the mission, such as the available bandwidth, the required data rate, and the acceptable error rate.
