Abstract: This application discloses a method and an apparatus for processing information, a communications device, and a communications system. The communications device is configured to obtain a starting position of an output bit sequence in a coded block in a circular buffer, and determine the output bit sequence in the coded block based on a length of the output bit sequence and the starting position. A value of the starting position is one of {p0, p1, p2 . . . , pkmax−1}, where 0≤pk

Abstract: This application discloses a data transmission method, a sending device, a receiving device, and a communications system. The sending device is configured to send a first transport block. The sending device obtains a coded bit segment from a first encoded code block. The first encoded code block is obtained after LDPC encoding is performed on a first code block in the first transport block based on a processing capability of the receiving device. The sending device sends the coded bit segment to the receiving device. Because the processing capability of the receiving device is considered, storage overheads of the sending device or the receiving device can be reduced, encoding or decoding complexity can be reduced, and a decoding success rate can be improved.

Abstract: The present disclosure relates to methods and apparatuses for generating a low-density parity-check code basis matrix. One example method includes obtaining a low-density parity-check code mother matrix, and generating a 1st matrix to a qth matrix one by one, where q is a preset positive integer. A Pth matrix in the 1st matrix to the qth matrix is generated in the following manner: selecting a to-be-replaced matrix element in a (P−1)th matrix, where the to-be-replaced matrix element is a matrix element having a value that is not −1 in the (P−1)th matrix, determining a Pth shift factor corresponding to the to-be-replaced matrix element, and replacing the to-be-replaced matrix element in the (P−1)th matrix with the Pth shift factor to obtain the Pth matrix whose cycle length property is better than a cycle length property of the (P−1)th matrix.

Abstract: Embodiments disclose a channel decoding method and apparatus, and a distributed decoder. A channel decoding apparatus includes: a decoding information acquiring unit, configured to acquire demodulation information of a channel; a channel decoding algorithm unit, configured to decode the demodulation information to obtain current decoding information, and perform a cyclic redundancy check CRC check on the current decoding information to obtain a current decoding CRC check result; and a lower level decoding determining unit, configured to: if the current decoding CRC check result is incorrect and a lower level channel decoding apparatus exists, determine that the lower level channel decoding apparatus continues to decode the demodulation information, where decoding performance of a channel decoding algorithm unit in the lower level channel decoding apparatus is superior to decoding performance of the channel decoding algorithm unit in the channel decoding apparatus.

Abstract translation: 实施例公开了一种信道解码方法和装置以及分布式解码器。 信道解码装置包括：解码信息获取单元，用于获取信道的解调信息; 信道解码算法单元，被配置为对解调信息进行解码以获得当前解码信息，并对当前解码信息执行循环冗余校验CRC校验，以获得当前解码CRC校验结果; 以及下层解码判定部，其特征在于：如果当前的解码CRC检查结果不正确，存在较低级别的信道解码装置，则判定下层信道解码装置继续对解调信息进行解码， 低级信道解码装置中的解码算法单元优于信道解码装置中的信道解码算法单元的解码性能。
