Title (EN) ENCODING AND DECODING FOR MESSAGES WITH PARTIAL COMMON CONTENT
(FR) CODAGE ET DÉCODAGE DE MESSAGES À CONTENU COMMUN PARTIEL
Abstract:
(EN) Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for encoding and decoding of transmission with partial common content. The described techniques leverage the mathematical properties of a linear encoding operation to reduce encoding and decoding complexity without a significant deterioration in coding gain and system throughput. In aspects, a device that receives multiple codewords that contain a common portion may jointly process the codewords to decode the variable portion, the common portion, or both. The described techniques may in some cases be supported through the use of differential encoding, which may support the efficient joint processing of the codewords. In some cases, the encoding and decoding techniques may be based on a nested coding design, which may improve the coding gain of the system.
(FR) La présente invention concerne des procédés, des systèmes et des dispositifs de communications sans fil. D'une manière générale, les techniques selon l'invention permettent de coder et de décoder une transmission comprenant un contenu commun partiel. L'invention exploite les propriétés mathématiques d'une opération de codage linéaire pour réduire la complexité de codage et de décodage sans perte remarquable dans le gain de codage et le débit de système. Selon certains aspects, un dispositif qui reçoit de multiples mots de code contenant une partie commune peut traiter conjointement les mots de code pour décoder la partie variable et/ou la partie commune. Les techniques selon l'invention peuvent dans certains cas être mises en œuvre au moyen d'un codage différentiel, qui peut mettre en œuvre le traitement conjoint efficace des mots codés. Dans certains cas, les techniques de codage et de décodage peuvent être fondées sur une conception de codage imbriquée, qui peut améliorer le gain de codage du système.
