Abstract
This application discloses an information processing method and apparatus, a communications device, and a communications system. The method includes: encoding an input sequence by using a low density parity check LDPC matrix to obtain a bit sequence D, where a base matrix of the LDPC matrix is represented by a matrix of m rows and n columns, each column corresponds to a group of Z continuous bits in the bit sequence D, and both n and Z are integers greater than 0; and obtaining an output bit sequence based on a bit sequence V, where the bit sequence V is obtained by permuting groups of bits corresponding to at least two parity check columns in the bit sequence D.
