Bitpermutationsmønstre til LDPC-kodet modulation og 64QAM-konstellationer |
| 摘要 |
<p>The present invention relates to methods for digital signal processing and to transmission/reception systems utilizing said methods; the present invention is based on the use of LDPC codes, in particular the LDPC code with a 3/5 code rate, in combination with a QAM modulation, in particular the 16QAM or 64QAM or 256QAM modulation; in transmission, a bit permutation (Demux) is carried out prior to the QAM constellation mapping function; in reception, the bit permutation is carried out after the QAM constellation demapping function.</p> |
