Title (EN) TRANSMISSION TIMING OFFSET METHOD FOR DS-CDMA MOBILE TELEPHONE SYSTEMS
(FR) PROCEDE DE DECALAGE DES POSITIONNEMENTS TEMPORELS DE TRANSMISSION POUR SYSTEMES RADIOTELEPHONIQUES MOBILES A ACCES MULTIPLE PAR DIFFERENCE DE CODE EN SEQUENCE DIRECTE (AMDCSD)
Abstract: front page image
(EN)A method for altering transmission timings among a plurality of parallel discontinuous transmissions (50) is disclosed. In a DS-CDMA system having a plurality of discontinuous slot-wise transmissions (50), each transmission connection is offset by a predetermined amount in order to generate interference that is evenly spread in time between cells.
(FR)L'invention concerne un procédé pour modifier les positionnements temporels des transmissions parmi une pluralité de transmissions discontinues parallèles (50). Dans un système AMDCSD comportant une pluralité de transmissions discontinues par tranche de temps (50), chaque liaison de transmission est décalée d'une valeur prédéterminée en vue de créer entre les cellules des interférences qui soient réparties uniformément dans le temps.
