A method and an apparatus for decoding low-density parity-check codes are provided. The method includes the following: A first decoding unit performs decoding computation on a first code word from a second time period to an O th time period; a second decoding unit performs decoding computation on a second code word from a third time period to an (O+1) th time period; an N th decoding unit performs decoding computation on an N th code word from an (N+1) th time period to an (N+O-1) th time period; and an M th decoding unit performs decoding computation on an M th code word from an (M+1) th time period to an (M+O-1) th time period. Each decoding unit may perform decoding computation in multiple time periods, so that the iteration time of decoding computation is adjusted according to a decoding algorithm and the channel status, and the number of iterations is thereby effectively increased to ensure the decoding performance. Multiple decoding units may work simultaneously without interfering with each other, and thereby the processing quantity of data is effectively increased, so that the decoding rate can meet the current demand for rapid expansion of the network bandwidth. |
