Title (EN) METHOD OF TRANSMITTING DATA FOR DIGITAL BROADCASTING IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ DE TRANSMISSION DE DONNÉES POUR RADIODIFFUSION NUMÉRIQUE DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract: front page image
(EN)A method of transmitting data in a wireless communication system includes mapping first data to first symbols on a signal constellation, mapping second data assisting the first data to second symbols on the signal constellation, modulating the first symbols and the second symbols, and transmitting the modulated first symbols and the second symbols, wherein the distance between the first symbols is longer than that between the second symbols on the signal constellation.
(FR)L'invention concerne un procédé de transmission de données dans un système de communication sans fil. Ce procédé consiste à mapper des premières données en premiers symboles sur une constellation de signaux; à mapper des deuxièmes données assistant les premières données en deuxièmes symboles sur la constellation de signaux; à moduler les premiers symboles et les deuxièmes symboles; et à transmettre les premiers et les deuxièmes symboles modulés, la distance entre les premiers symboles étant plus longue que celle séparant les deuxièmes symboles sur la constellation de signaux.
