Cet article propose un filtre d'annulation du domaine fréquentiel et un égaliseur Turbo pour supprimer les interférences dans la liaison montante des systèmes à accès multiple par répartition dans le temps (TDMA) à porteuse unique et à réutilisation d'une seule cellule. Dans le système proposé, le signal souhaité dans une cellule de référence est brouillé par des signaux d'interférence comprenant une interférence de canal adjacent (ACI), une interférence dans le même canal (CCI) et une interférence intersymbole (ISI). Au niveau de l'émetteur, après qu'une certaine quantité de spectre a été annulée compte tenu du CCI attendu, la puissance supprimée en raison de l'annulation est réattribuée aux composants de spectre restants de manière à maintenir constante la puissance d'émission totale. Dans ce processus, lorsque l'atténuation de l'ACI est nécessaire, après qu'une certaine quantité de spectre au niveau des deux bords ait été annulée à l'aide d'un filtre de suppression de bord, le processus susmentionné est effectué. Au niveau du récepteur, un égaliseur turbo SC/MMSE (FDTE) dans le domaine fréquentiel est utilisé pour supprimer l'ISI en raison du processus d'annulation du spectre dans l'émetteur ainsi que de l'évanouissement par trajets multiples. Les simulations informatiques confirment que le schéma proposé est efficace pour supprimer les CCI, ACI et ISI dans les systèmes TDMA monoporteuse à réutilisation d'une cellule.

Abstract: This paper proposes a frequency domain nulling filter and Turbo equalizer to suppress interference in the uplink of one-cell reuse single-carrier time division multiple access (TDMA) systems. In the proposed system, the desired signal in a reference cell is interfered by interference signals including adjacent-channel interference (ACI), co-channel interference (CCI), and intersymbol interference (ISI). At the transmitter, after a certain amount of spectrum is nulled considering the expected CCI, the suppressed power due to nulling is reallocated to the remaining spectrum components so as to keep the total transmit power constant. In this process, when mitigation of ACI is necessary, after a certain amount of spectrum at both edges is nulled using an edge-removal filter, the aforementioned process is conducted. At the receiver, frequency domain SC/MMSE Turbo equalizer (FDTE) is employed to suppress ISI due to spectrum nulling process in the transmitter as well as the multipath fading. Computer simulations confirm that the proposed scheme is effective in suppression of CCI, ACI and ISI in one-cell reuse single-carrier TDMA systems.
