Title (EN) APPARATUS, AND ASSOCIATED METHOD, FOR TRANSMITTING AND RECEIVING A MULTI-STAGE, ENCODED AND INTERLEAVED DIGITAL COMMUNICATION SIGNAL
(FR) DISPOSITIF ET PROCEDE D'EMISSION ET DE RECEPTION D'UN SIGNAL DE COMMUNICATION NUMERIQUE ENTRELACE A CODAGE MULTINIVEAU
Abstract: front page image
(EN)Apparatus (50) and associated method for improving the radio link performance of a radio communication system, such as a cellular communication system (10). Multi-stage encoding (32, 42) and interleaving (36, 46) of the data bits of a digital information signal is performed at a single logical device, such as a radio base station (12). By performing two stages of interleaving (36, 46) over the same number of information frames of the data bits, only a single buffering state is required to perform such multi-stage interleaving.
(FR)L'invention concerne un dispositif (50) et un procédé permettant d'améliorer le rendement des liaisons radio d'un système de radiocommunication tel qu'un système de communications cellulaire (10). Le codage multi-niveau (32, 42) et l'entrelacement (36, 46) des bits de données d'un signal d'information numérique sont effectués au niveau d'un dispositif logique unique tel qu'une station de base radio (12). La réalisation de deux niveaux d'entrelacement (36, 46) sur le même nombre de trames d'informations contenant des bits de données permet d'utiliser un seul niveau de mise en tampon pour réaliser un tel entrelacement multi-niveau.
