Cet article présente une comparaison des performances de débit en utilisant une demande de répétition automatique hybride (HARQ) avec une combinaison de paquets, telle que le type I avec combinaison de paquets (simplement une combinaison de Chase ci-après) et le type II (redondance incrémentale ci-après), en utilisant le turbocodage dans un canal à évanouissement multivoie dans l'accès par paquets de liaison descendante à haut débit (HSDPA). Nous appliquons un annuleur d'interférences multi-trajets (MPIC) pour supprimer l'influence des interférences multi-trajets graves. Les résultats de simulation au niveau de la liaison montrent que le débit maximum utilisant la redondance incrémentale avec 64QAM est amélioré d'environ 5 à 8 % par rapport à celui utilisant la combinaison Chase, et que l'énergie moyenne requise du signal reçu de 12 canaux de code par puce à densité spectrale de bruit de fond (Ec/N0) au débit de 4 Mbps avec redondance incrémentale est diminué d'environ 1.0 dB plutôt qu'avec la combinaison Chase lorsque la vitesse du véhicule est supérieure à environ 30 km/h. En outre, nous expliquons, sur la base de la simulation au niveau du système, que même si aucune amélioration n'est obtenue dans un environnement de mobilité lente tel que la vitesse moyenne des véhicules de 3 km/h, le débit atteint de redondance incrémentale est augmenté d'environ 5 à 6 % et 13 %. pour une vitesse moyenne des véhicules de 30 km/h et 120 km/h, respectivement, par rapport à celle avec la combinaison Chase.

Abstract: This paper presents a comparison of the throughput performance employing hybrid automatic repeat request (HARQ) with packet combining, such as Type-I with packet combining (simply Chase combining hereafter) and Type-II (Incremental redundancy hereafter), using turbo coding in a multipath fading channel in high speed downlink packet access (HSDPA). We apply a multipath interference canceller (MPIC) to remove the influence of severe multipath interference. Link level simulation results show that the maximum throughput using Incremental redundancy with 64QAM is improved by approximately 5-8% compared to that using Chase combining, and that the required average received signal energy of 12 code channels per chip-to-background noise spectrum density (Ec/N0) at the throughput of 4 Mbps with Incremental redundancy is decreased by approximately 1.0 dB rather than that with Chase combining when the vehicular speed is higher than approximately 30 km/h. Furthermore, we elucidate based on the system level simulation that although no improvement is obtained in a slow mobility environment such as the average vehicular speed of 3 km/h, the achieved throughput of Incremental redundancy is increased by approximately 5-6% and 13% for the average vehicular speed of 30 km/h and 120 km/h, respectively, compared to that with Chase combining.
