    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

    Abstract: This application discloses an information processing method. A communication device obtains an input sequence. The input sequence has a quantity B of information bits. The communication devices transforms the input sequence into one or more code blocks. The communication device encodes each of the code blocks individually, to obtain one or more encoded code blocks. Each of the code blocks has a code block length less than or equal to a maximum code block length. Each of the code blocks includes a segment of the input sequence and may include one or more cyclic redundancy check (CRC) bits corresponding to the segment of the input sequence. The encoded code blocks can meet various channel coding requirements.

    Abstract: This application relates to communicating information between communication devices. A channel coding method is disclosed. A communication device obtains an input sequence of K bits. The communication device encodes the input sequence using a low density parity check (LDPC) matrix H, to obtain an encoded sequence. The LDPC matrix H is determined according to a base matrix and a lifting factor Z. The base matrix includes m rows and n columns, m is greater than or equal to 5, and n is greater than or equal to 27. The lifting factor Z satisfies a relationship of 22*Z≥K. According to the encoding method provided in the embodiments, information bit sequences of a plurality of lengths can be encoded for transmission between the communication devices.

    Abstract: An antenna includes a first antenna having a first feeding portion and at least one stub, and a second antenna having a second feeding portion and at least one stub. The first feeding portion is disposed on a first side of a first diagonal line of the rectangular region. The at least one stub of the first antenna extends from the first feeding portion in a first direction. A first angle is between the first direction and a long-edge direction of the rectangular region. The second feeding portion is disposed on a second side of the first diagonal line of the rectangular region. The at least one stub of the second antenna extends from the second feeding portion in a second direction. A second angle is between the second direction and the long-edge direction of the rectangular region and is different from the first angle.
