  • Publication number: 20190181883
    Abstract: The present disclosure relates to a communications field, and discloses a method for generating a base matrix of an LDPC code, an encoding/decoding method, and a device, to resolve a problem that a probability of a decoding error increases because performance of a transformed check matrix cannot be ensured due to a poor puncturing pattern. A specific solution is as follows: A size of a check bit part of a base matrix is determined based on a required minimum bit rate, and the check bit part of the base matrix is determined based on the size of the check bit part and an initial matrix. The initial matrix is a matrix with a size of m×m that has a bidiagonal structure, the check bit part is a k-order transformation matrix Hk obtained after the initial matrix is transformed k times, k meets 2k?1m<T?2km, and T is the size of the check bit part.
