ERROR CORRECTION METHOD AND APPARATUS

摘要

Error Correction Method and Apparatus For forward error correction, the least significant bit of each multibit symbol is encoded before transmission according to a block code that has an over-all parity bit. Since even syndromes can be produced by only an even number of errors and odd syndromes by an odd number of errors, a Chase decoder at the receiver considers either all double errors or all single errors and all triple errors that include the least reliable symbol in making the corrections to arrive at the most likely transmitted sequence.
