An adaptive fusion serial cancellation list polarization code decoding method and system

ActiveCN109921804AJudgment valueAverage complexity neutralCyclic codesSignal-to-noise ratio (imaging)Coding decoding
The invention discloses a self-adaptive fusion serial cancellation list polarization code decoding method and a self-adaptive fusion serial cancellation list polarization code decoding system. The method comprises the following steps: obtaining bits in a to-be-decoded sequence; screening out information bits in the sequence to be decoded; judging whether the log-likelihood ratio of each information bit meets a positive threshold judgment condition which is greater than 0 and greater than a positive threshold or a negative threshold judgment condition which is less than 0 and less than a negative threshold one by one according to the arrangement sequence of the coded bit sequence to obtain a first judgment result; when the first judgment result is negative information bits, the informationbits of which the arrangement sequence is before the information bits of which the first judgment result is negative are decoded one by one by adopting a serial offset decoding method; and decoding the information bits with the first judgment result being no and all the bits behind the information bits one by one by adopting a cyclic redundancy auxiliary serial offset list decoding method. According to the invention, the average complexity of the adaptive serial cancellation list decoding method under a low signal-to-noise ratio can be reduced, and the low average complexity under a high signal-to-noise ratio can be maintained.

The invention relates to the field of fluororubber synthesis, and especially relates to peroxide vulcanized fluororubber and a preparation method thereof. The preparation method of the peroxide vulcanized fluororubber comprises the following step: carrying out polymerization reaction by taking vinylidene fluoride, tetrafluoroethylene and hexafluoropropylene as mixed monomers, wherein in the polymerization reaction process, the mole number of tetrafluoroethylene in a reaction kettle is always kept to be 15-25% of the total mole number of the mixed monomers, and the mole numbe of hexafluoropropylene in the reaction kettle is always kept to be 25-35% of the total mole numbe of the mixed monomers. The obtained peroxide vulcanized fluororubber has high fluorine content and low compression deformation at the same time; the problem that the cross-linking density of peroxide vulcanized fluororubber with high fluorine content is reduced in the vulcanization processing process due to non-uniform distribution of TFE and HFP in a molecular chain segment in the polymerization process is effectively solved; and meanwhile, the reaction time is controlled to be shorter, so that the branching reaction is prevented, the effectiveness of a monomer at a vulcanization point in a chain link is ensured, and the problem of higher compression deformation is solved.
