CA 2336820

An effective data multiplexing method wherein an error correction ability is exerted at the maximum so that data transmission quality is improved and a data transmitting method in which an interleaving process applicable to data transmission using interpolation pilot signal is performed are provided. The data multiplexing method includes the steps of: coding input data for each input channel; multiplexing said data which is coded; performing an interleaving process on said data which is multiplexed; and outputting said data. In the data transmitting method, when an interleaving process is performed, an interleaves is used in which the number of columns of the interleaver is twice as many as the number of slots of a frame.

La présente invention concerne un procédé de multiplexage efficace permettant de réaliser un maximum de correction d'erreurs pour améliorer la qualité de la transmission de données, et un procédé de transmission de signaux de données permettant d'effectuer un processus d'entrelacement convenant à un procédé de transmission de signaux de données utilisant des signaux pilotes d'interpolation. Ce procédé d'entrelacement code des données d'entrée pour chaque canal d'entrée, procède au multiplexage des données codées, effectue un processus d'entrelacement, pour des rangées de randomisation, sur les données multiplexées et produit des données en sortie. En outre, ce procédé de transmission de signaux de données utilise, dans un processus d'entrelacement, des dispositifs d'entrelacement dont le nombre est égal au double de celui des créneaux temporels dans une trame.
