This invention discloses a low-power, high-throughput 5G LDPC decoder implementation method, specifically comprising: Step 1, calculating the parameters required for decoding from the input parameters; Step 2, based on the spreading factor Z... c The values ​​are stored in different blocks according to different storage methods; Step 3: Based on the expansion factor Z c The value of determines whether to perform layer splitting transformation on the base matrix and update the required posterior probability information of the variable nodes; Step 4: Update the information of the check nodes and the posterior probability information of the variable nodes within the layer; Step 5: Implement layered iterative decoding; Step 6: After updating the information of all check nodes in each layer and reaching the set number of iterations, the decoding iteration is completed, and the output processing of the decoding result begins. This method significantly reduces the required resources; and by utilizing the orthogonality of adjacent layers of the split matrix, the intra-layer pipelining operation improves the decoder throughput after reducing the decoding parallelism. A low-consumption, high-throughput 5G LDPC decoder implementation device is also disclosed.
