    Abstract: A data processing method based on a quasi-cyclic LDPC includes: when a size of service data is less than a magnitude of information bit of the quasi-cyclic LDPC, calculating a difference value between the magnitude of the information bit of the quasi-cyclic LDPC and the size of the service data, and filling the service data with the same amount of known data as the difference value (S103); coding the filled service data to obtain redundancy check data corresponding to the service data (S104); and sending the service data and the redundancy check data to a corresponding physical location in the storage unit (S105). It ensures that when a code length of the quasi-cyclic LDPC is constant, the code length ideally adapts to internal space of the storage unit, and the quasi-cyclic LDPC has a relatively high error correction capability, thereby improving reliability and service life of the storage unit.

    Abstract: Embodiments of the present invention provide a method and an apparatus for dynamic spectrum management. The method includes: determining a reusable spectrum for one of multiple cell links in a network according to co-frequency indication information, where the co-frequency indication information is used to indicate reusable levels of spectrums of other cell links for each cell link in the multiple cell links; and updating a spectrum configuration of the one of the multiple cell links by using the reusable spectrum of the one of the multiple cell links. By determining a reusable spectrum for a specific cell link according to co-frequency indication information, embodiments of the present invention can locally adjust the spectrum configuration of the specific cell link, thereby reducing a spectrum configuration overhead while increasing network capacity and reducing inter-cell interference.

    Abstract: Embodiments of the present disclosure provide a decoding method of a polar code, including: acquiring a receiving sequence and a check matrix, wherein the receiving sequence is output on a channel after an input mapping sequence is encoded; carrying out Trellis path search according to the receiving sequence and the check matrix, and calculating Trellis path likelihood information corresponding to the input mapping sequence; calculating a decision value corresponding to the input mapping sequence according to the Trellis path likelihood information; and de-mapping the calculated decision value corresponding to the input mapping sequence according to a preset mapping relation to obtain a decoding sequence. The input mapping sequence belongs to a finite field GF(q), when decoding the polar code, the Trellis path search is carried out, and the decision value is calculated and de-mapped to simultaneously reduce a maximum list value and greatly reduce an average list value.
