DATA PROCESSING METHOD AND SYSTEM BASED ON QUASI-CYCLIC LDPC |
摘要 |
A data processing method and system based on quasi-cyclic LDPC. The method comprises: calculating the size of an information bit of the quasi-cyclic LDPC (S101); acquiring service data having the same space size as that of service data in a storage unit (S102); when the size of the service data is less than the size of the information bit of the quasi-cyclic LDPC, calculating a difference value between the size 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); encoding 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). The solution can ensure that in the case where the length of a quasi-cyclic LDPC code is fixed, the code is ideally adapted to the internal space of a storage unit, and has a higher error correction capability, which increases the reliability and the service life of the storage unit. |
