Title:
DATA TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/137544
Kind Code:
A1
Abstract:
The present application provides a data transmission method and apparatus. The method comprises: a transmitting device encodes an information bit sequence to be transmitted by using an LDPC check matrix to obtain a transmission sequence after encoding, wherein the LDPC check matrix is obtained by transforming a preset base matrix to obtain a base matrix corresponding to the code rate of the information bit sequence and then transforming the obtained base matrix again; the transmitting device transmits the transmission sequence to a receiving device. In the solution, it does not need to design LDPC base matrices for different code rates, and a basic matrix corresponding to a required code rate can be obtained by means of simple transformation of a preset base matrix. Thus, the system complexity and the encoding complexity are reduced.
