Cet article étudie la meilleure structure de signal de référence (RS) commun à une cellule et le meilleur schéma de diversité de transmission pour les signaux du service de diffusion multidiffusion multimédia (MBMS) en tenant compte de la diversité de fréquence dans un réseau monofréquence (SFN) dans la liaison descendante UTRA évoluée basée sur l'OFDM. Les résultats de simulation au niveau de la liaison montrent que la diversité de retard cyclique (CDD) est le schéma de diversité de transmission le plus prometteur pour les signaux MBMS, compte tenu du surdébit RS. Il est également précisé que l'énergie moyenne requise du signal reçu par rapport de densité spectrale de puissance symbole sur bruit (Es/N0) utilisant CDD est réduit d'environ 0.5 dB même si le signal MBMS obtient un gain de diversité de fréquence suffisant en fonctionnement SFN. En outre, nous clarifions le débit de données réalisable pour le signal MBMS au bord de la cellule MBMS centrée qui satisfait au taux d'erreur de bloc requis (BLER) en utilisant un CDD de transmission à deux antennes et une réception en diversité par simulation au niveau du système. Ensuite, les résultats de la simulation montrent que les débits de données proposés avec un BLER requis inférieur à 10-2 à 95 % de couverture, les valeurs sont 0.211 (0.17), 0.243 (0.196), 1.168 (1.084) et 2.754 (2.754) bps/Hz avec le nombre de cellules fournissant du MBMS, NMBMS = 1, 3, 21 et 57, respectivement, en utilisant un CDD d'émission avec deux antennes (transmission à antenne unique) pour ISD = 500 m.

Abstract: This paper investigates the best cell-common reference signal (RS) structure and transmit diversity scheme for Multimedia Broadcast Multicast Service (MBMS) signals considering frequency diversity in a single-frequency network (SFN) in the OFDM based Evolved UTRA downlink. Link-level simulation results show that cyclic delay diversity (CDD) is the most promising transmit diversity scheme for the MBMS signals considering the RS overhead. It is also elucidated that the required average received signal energy per symbol-to-noise power spectrum density ratio (Es/N0) using CDD is reduced by approximately 0.5 dB even though the MBMS signal obtains a sufficient frequency diversity gain in SFN operation. Furthermore, we clarify the achievable data rate for the MBMS signal at the cell edge of the centered MBMS cell that satisfies the required block error rate (BLER) using two-antenna transmit CDD and diversity reception by system-level simulation. Then, the simulation results show that the offered data rates with the required BLER of less than 10-2 at 95% coverage are 0.211 (0.17), 0.243 (0.196), 1.168 (1.084), and 2.754 (2.754) bps/Hz with the number of cells providing MBMS, NMBMS = 1, 3, 21, and 57, respectively, employing transmit CDD with two antennas (single-antenna transmission) for ISD = 500 m.
