Abstract:
1. An iterative decoding method, comprising: sequentially executing a number of iterative decoding cycles in relation to a parity check equation until the parity check equation is resolved, or a maximum number N of iterative decoding cycles is reached; during execution of the number of iterative decoding cycles, storing in a data buffer minimum estimated values for a set of variable nodes corresponding to a minimum number of bit errors, wherein the minimum estimated values correspond to a decoding result having a minimum number of error bits; and outputting the minimum estimated values stored in the data buffer as a final decoding result when the number of iterative decoding cycles reaches N, wherein the minimum estimated values stored in the data buffer are different from estimated values for the set of variable nodes as determined in a final cycle among the N iterative decoding cycles.
