  • Patent number: 5995559
    Abstract: Instead of simply taking a bit-wise majority vote of several received encoded data words and decoding the result of the vote, the chances of usefully decoding a word may be increased by decoding every word received. If a received word is decoded as correct or with a corrected one-bit error or with a corrected two-bit error, this decoded word can be used as the received word. Also, bit-wise majority votes can be taken on all combinations of small groups of the received words, and the results passed to the decoder. If the decoder reports a correct word or a word having a one-bit or two-bit error corrected for one of these combinations, this can be used as the received word. Error-correction beyond the typical capabilities of a BCH code can be realized if the error-correction decoder is properly configured. "Word-wise" majority voting is also described.
