DECODING EXTENDED ERROR CORRECTING CODES USING SOFT INFORMATION |
摘要 |
In one embodiment, the present invention can be used to correct one more error in an extended codeword encoded with a block code and a single parity check code than the block code is able to correct. In one embodiment, a communications device includes a decoder that has a soft decoder to receive an extended codeword and a strength of each bit of the extended codeword, and to produce a codeword by soft decoding the extended codeword using the received strengths, and a block decoder coupled to the soft decoder to produce a corrected codeword by block decoding the codeword using an error correcting block code. |
