  • LOW DENSITY PARITY CHECK CODE DECODER AND DECODING METHOD THEREOF
    Publication number: 20190165811
    Abstract: An LDPC decoder determines j number of variable nodes related to a first check node based on a parity check matrix. The LDPC decoder calculates j number of node LLR values corresponding to the j number of variable nodes, and determines j number of initial CN-VN LLR values of the j number of variable nodes. The LDPC decoder calculates j number of VN-CN LLR values according to the j number of node LLR values and the j number of initial CN-VN LLR values, and calculates j number of updated CN-VN LLR values of the j number of variable nodes. The LDPC decoder calculates j number of updated node LLR values according to the j number of updated CN-VN LLR values and j number of VN-CN LLR values, and updates the j number of node LLR values of the j number of variable nodes by the updated node LLR values.
