DATA TRANSMISSION METHOD, SENDING DEVICE, AND RECEIVING DEVICE

Title:

DATA TRANSMISSION METHOD, SENDING DEVICE, AND RECEIVING DEVICE

Document Type and Number:

WIPO Patent Application WO/2018/119700

Kind Code:

A1

Abstract:

A data transmission method, a sending device, and a receiving device. The sending device obtains information data; the sending device encodes the information data by using quasi-cyclic low-density parity-check (LDPC) matrices, and the sending device modulates the encoded data to obtain first data; and the sending device sends the first data. The receiving device receives second data, and demodulates the second data to obtain data to be decoded; the receiving device decodes the data to be decoded by using block matrices among the quasi-cyclic low-density parity-check (LDPC) matrices, the block matrices being part of the quasi-cyclic LDPC matrices, the row weight of an (H-1)th row among the quasi-cyclic LDPC matrices being greater than or equal to that of an Hth row, or the row weight of the(H-1)th row being less than or equal to that of the Hth row. The decoding efficiency can be improved.
