Abstract
Disclosed herein is a decoding apparatus that performs soft-decision decoding on a linear block code, the apparatus including a hard-decision decoder configured to perform hard-decision decoding on a received word using a hard-decision decoding algorithm; and a soft-decision decoder configured to perform, using a soft-decision algorithm, soft-decision decoding merely on a received word for which the hard-decision decoder has failed in the hard-decision decoding.
Claims12
A decoding apparatus that performs soft-decision decoding on a linear block code, the apparatus comprising:
- a hard-decision decoder configured to perform hard-decision decoding on a received word using a hard-decision decoding algorithm;
- and
- a soft-decision decoder configured to perform, using a soft-decision algorithm, soft-decision decoding merely on a received word for which said hard-decision decoder has failed in the hard-decision decoding.
A decoding method for performing soft-decision decoding on a linear block code, the method comprising the steps of:
- first applying a hard-decision decoding algorithm to a received word to perform hard-decision decoding on the received word;
- and
- applying a soft-decision algorithm merely to a received word for which the hard-decision decoding may be impossible to perform the soft-decision decoding on that received word.
