Abstract
(EN) 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.
(FR) La présente invention concerne un procédé et un appareil de transmission de données. Le procédé comprend les étapes suivantes : un dispositif de transmission code une séquence de bits d'informations à transmettre au moyen d'une matrice de contrôle LDPC afin d'obtenir une séquence de transmission après codage, la matrice de contrôle LDPC étant obtenue en transformant une matrice de base prédéfinie en vue d'obtenir une matrice de base correspondant au débit de code de la séquence de bits d'information, puis en transformant de nouveau la matrice de base obtenue ; le dispositif de transmission transmet la séquence de transmission à un dispositif de réception. La solution selon l'invention évite la nécessité de concevoir des matrices de base LDPC pour des débits de code différents et une matrice de base correspondant à un débit de code exigé peut être obtenue au moyen d'une transformation simple d'une matrice de base prédéfinie. La complexité du système et la complexité de codage sont ainsi réduites.
