The invention relates to an information processing method of low-density check codes, which belongs to the field of communication technology. The method comprises the steps of: carrying out swivel adjustment on a check matrix H1 of the low-density check codes by a sending terminal to obtain a processed matrix H2; sending an initial data vector V by using a low-density check code encoder accordingto the matrix H2 to obtain a codeword vector X and sending the codeword vector X through channel; receiving a codeword vector Y by a receiving terminal and storing the codeword vector Y in a decoder buffer directly according to the order of reception; and receiving and processing the codeword vector Y by the receiving terminal by using the present layered low-density check code decoder to obtain a codeword vector Z, and then outputting the codeword vector Z directly according to the order of reception. The invention omits the input and output cyclic shift network for the low-density check code decoder, reduces the are
