ABSTRACT:
Decoding performance of threshold-decodable forward-error-correcting codes is improved through the use of three methods. These methods employ measurements of received-digit reliability, and extended examination of syndrome digits. The first disclosed method allows correction of most partially-masked channel errors. These errors are not corrected in the prior art. The second and third disclosed methods correct almost all channel correctable with prior art, but furthermore disable action by the decoder in most cases where prior art would erroneously alter an information digit that had been received correctly.
