Title (EN) METHOD AND WIRELESS COMMUNICATIONS SYSTEMS USING COORDINATED TRANSMISSION AND TRAINING FOR INTERFERENCE MITIGATION
(FR) PROCEDE ET SYSTEMES DE COMMUNICATION SANS FIL PAR TRANSMISSION COORDONNEE ET ENTRAINEMENT A L'ATTENUATION D'INTERFERENCES
Abstract: front page image
(EN)A method for interference mitigation in a wireless communication system having multiple transmitters (15A, 15B, 15C) and receivers by introducing transmission time delays between the transmission of signals (S1, S2, and S3) from the individual transmitters (15A or 15B or 15C) to ensure coherent reception of the signals at a specific point (CD) in the coverage area. To further aid in interference mitigation the signals are assigned training patterns chosen to be distinguishable by the receiver and to optimize interference mitigation.
(FR)L'invention concerne un procédé d'atténuation d'interférences dans un système de communication sans fil possédant des émetteurs (15A, 15B, 15C) et des récepteurs multiples, en introduisant des délais de transmission entre les signaux (S1, S2, et S3) à partir d'émetteurs individuels (15A ou 15B ou 15C), afin d'assurer une réception cohérente des signaux, en un point spécifique (CD) de la zone de couverture. On associe lesdits signaux à des motifs d'entraînement, sélectionnés afin que le récepteur puisse les distinguer et que cela permette d'optimiser l'atténuation d'interférences.
