Il est bien connu que les performances de la méthode de détection de signal à annulation d'interférence successive ordonnée (OSIC) dépendent de la détection réussie de la première couche. Dans un travail précédent, dans le but d'atténuer l'effet de propagation des erreurs, tous les points de la constellation ont été essayés comme symbole de première couche, obtenant ainsi de meilleures performances. Dans cette lettre, nous montrons que la sélection de la première couche a un impact significatif sur les performances d'erreur, et sur la base de l'observation, nous proposons une nouvelle méthode de détection de signal. QR-LRL. Dans le travail proposé, la couche la moins fiable (LRL) est choisie comme première couche, ce qui s'avère être le meilleur choix en termes d'amélioration du bruit dans la détection des autres couches. Nous discutons également du calcul du rapport de vraisemblance (LLR) lorsque la méthode proposée est utilisée. Les simulations informatiques confirment l'efficacité de la méthode proposée.

Abstract: The performance of the ordered successive interference cancellation (OSIC) signal detection method is well known to depend on the successful detection of the first layer. In a previous work, in an effort to mitigate the error propagation effect, all the constellation points were tried as the first layer symbol, thereby achieving a better performance. In this letter, we show that the selection of the first layer impacts the error performance significantly, and based on the observation, we propose a novel signal detection method QR-LRL. In the proposed work, the least reliable layer (LRL) is chosen to be the first layer, which is shown to be the best choice in terms of noise enhancement in detecting the other layers. Also, we discuss Log Likelihood Ratio (LLR) computation when the proposed method is used. Computer simulations confirm the efficacy of the proposed method.
