  • Encoder and decoder for LDPC code
    Patent number: 10536169
    Abstract: Disclosed relates to a decoder for LDPC code, including: a variable node processing unit; a check node processing unit; a memory for storing iterative messages of edges of a parity-check matrix for LDPC code; and a controller for controlling the node processing units to perform iterations of decoding until the decoding ends, wherein, in each iteration of decoding, the controller controls the variable node processing unit to compute variable node messages in a traversing manner for all variable nodes and updates the iterative messages in the memory according to the computed variable node messages, and controls the check node processing unit to compute check node messages in a traversing manner for all check nodes and updates the iterative messages in the memory according to the computed check node messages.
