QC-LDPC CODE DECODER AND CORRESPONDING DECODING METHOD

摘要

An efficient universal QC-LDPC code decoder includes a universal processor for distributing the storage space of the data memory block, and establishing an index for data addressing; a data memory block for storing the information used during decoding; a hardware accelerator for accomplishing part or all of the information processing operations which include parity check, check node updating and variable node updating. A corresponding QC-LDPC code decoding method includes initializing the variable node information and performing parity check on the check matrix row block by row block; updating the check node row block by row block and updating the variable node column block by column block if any check equation is not meet.
