Dans la liaison montante Evolved UTRA (UMTS Terrestrial Radio Access), l'accès radio à accès multiple par répartition en fréquence à porteuse unique (SC-FDMA) a été adopté en raison de sa caractéristique avantageuse de faible rapport puissance crête/puissance moyenne (PAPR), qui conduit à une large couverture. approvisionnement de zone avec une puissance de transmission de crête limitée des équipements utilisateur. Cet article propose la génération de canaux pilotes orthogonaux en utilisant la combinaison de FDMA et CDMA dans la liaison montante Evolved UTRA basée sur SC-FDMA. Dans le procédé proposé, nous utilisons une transmission FDMA distribuée pour les utilisateurs à accès simultané avec différentes bandes passantes de transmission, et nous utilisons la transmission CDMA pour les utilisateurs à accès simultané avec une bande passante de transmission identique. De plus, nous appliquons une séquence de code avec une bonne propriété d'auto-corrélation telle qu'une séquence d'auto-corrélation nulle à amplitude constante (CAZAC) employant un décalage cyclique pour augmenter le nombre de séquences. Les résultats de simulation montrent que les performances moyennes du taux d'erreur sur les paquets en utilisant un canal pilote orthogonal avec la combinaison de FDMA et CDMA dans un environnement à six utilisateurs, c'est-à-dire quatre utilisateurs avec chacun une bande passante de transmission de 1.25 MHz et deux utilisateurs chacun avec une bande passante de 5 MHz. bande passante de transmission, utilisant un turbocodage avec un taux de codage de R = 1/2 et la modulation de données QPSK et 16QAM coïncide bien avec celle d'un environnement mono-utilisateur avec la même bande passante de transmission. Nous montrons que la structure de canal pilote orthogonal proposée utilisant la combinaison de transmissions distribuées FDMA et CDMA et l'application de la séquence CAZAC est efficace dans la liaison montante Evolved UTRA basée sur SC-FDMA.

Abstract: In the Evolved UTRA (UMTS Terrestrial Radio Access) uplink, single-carrier frequency division multiple access (SC-FDMA) radio access was adopted owing to its advantageous low peak-to-average power ratio (PAPR) feature, which leads to wide coverage area provisioning with limited peak transmission power of user equipments. This paper proposes orthogonal pilot channel generation using the combination of FDMA and CDMA in the SC-FDMA-based Evolved UTRA uplink. In the proposed method, we employ distributed FDMA transmission for simultaneous accessing users with different transmission bandwidths, and employ CDMA transmission for simultaneous accessing users with identical transmission bandwidth. Moreover, we apply a code sequence with a good auto-correlation property such as a Constant Amplitude Zero Auto-Correlation (CAZAC) sequence employing a cyclic shift to increase the number of sequences. Simulation results show that the average packet error rate performance using an orthogonal pilot channel with the combination of FDMA and CDMA in a six-user environment, i.e., four users each with a 1.25-MHz transmission bandwidth and two users each with a 5-MHz transmission bandwidth, employing turbo coding with the coding rate of R = 1/2 and QPSK and 16QAM data modulation coincides well with that in a single-user environment with the same transmission bandwidth. We show that the proposed orthogonal pilot channel structure using the combination of distributed FDMA and CDMA transmissions and the application of the CAZAC sequence is effective in the SC-FDMA-based Evolved UTRA uplink.
