Reed-Solomon Code (RS Code)
The Reed-Solomon code (RS code) is a class of non-binary block error-correcting codes belonging to the Bose–Chaudhuri–Hocquenghem (BCH) family, in which coding is performed on symbols composed of multiple bits rather than on individual bits. RS codes are particularly effective at correcting burst errors, since a single symbol error may correspond to several consecutive bit errors.
Because RS codes operate on symbols over finite fields, they are well suited to use with m-ary modulation schemes and are widely employed in satellite communications as part of forward error correction systems, often in combination with other coding techniques.
