INFORMATION PROCESSING METHOD AND APPARATUS, AND COMMUNICATION DEVICE
FIG5 is a flowchart of an information processing method according to another embodiment of the present invention  FIG6 is a flowchart of an information processing method according to another embodiment of the present invention
FIG5 is a schematic flowchart of an information processing method according to another embodiment of the present invention, and the method may be applied to a channel on which LDPC encoding is used, and includes:501. Perform low-density parity-check LDPC decoding based on a first soft value sequence to obtain a bit sequence Ct.  FIG6 is a schematic flowchart of an information processing method according to another embodiment of the present invention. Alternatively, a shift t may be determined first, and then an LDPC code is decoded after being reversely circularly shifted by t bits. The method may be applied to a channel on which LDPC encoding is used, and includes:601. Perform reverse cyclic shift on a first soft value sequence based on a shift t and a lifting factor z to obtain a soft value sequence corresponding to a bit sequence D, where t is an integer greater than or equal to 0.
