摘要： Methods for digital signal processing and transmission/reception systems utilizing the methods based on the use of LDPC codes, for example a LDPC code with a 3/5 code rate, in combination with a QAM modulation, for example the 16QAM or 64QAM or 256QAM modulation. In transmission, a bit permutation (Demux) is carried out prior to the QAM constellation mapping function, and in reception, the bit permutation is carried out after the QAM constellation demapping function.
