Disclosed are an information processing method and device. The device comprises: one or a plurality of memories configured to store parameters of one basic parity check matrix set; and one or a plurality of processors configured to encode an information bit to be encoded or decode data to be decoded using a basic parity check matrix set Hb, wherein at least 50 percent of short 4-rings in the basic parity check matrixes Hb j1 in other basic parity check matrixes except Hb j0 are the same as the short 4-rings in the Hb j0 , where j0 is a fixed positive integer between 0 and L-1, L is the number of basic parity check matrixes contained in the basic parity check matrix set, and j1 is equal to 0, 1,..., j0-1, j0+1,..., L-1. |
