Title (EN) DESIGN OF SHIFT VALUES FOR QUASI-CYCLIC LDPC CODES
(FR) CONCEPTION DE VALEURS DE DÉCALAGE DE CODES LDPC QUASI-CYCLIQUES
Abstract:
(EN) According to some embodiments, a method for use in a wireless transmitter of a wireless communication network comprises encoding information bits using a parity check matrix (PCM) and transmitting the encoded information bits to a wireless receiver. The parity check matrix (PCM) is optimized according to two or more approximate cycle extrinsic message degree (ACE) constraints. In some embodiments, a first portion of the PCM is optimized according to a first ACE constraint and a second portion of the PCM is optimized according to a second ACE constraint.
(FR) Selon certains modes de réalisation, un procédé destiné à être utilisé dans un émetteur sans fil d'un réseau de communication sans fil consiste à coder des bits d'informations à l'aide d'une matrice de contrôle de parité (PCM) et à transmettre les bits d'informations codés à un récepteur sans fil. La matrice de contrôle de parité (PCM) est optimisée conformément à au moins deux contraintes de degré de message extrinsèque de cycle approximatif (ACE). Selon certains modes de réalisation, une première partie de la PCM est optimisée conformément à une première contrainte ACE et une seconde partie de la PCM est optimisée conformément à une seconde contrainte ACE.
