Dans cette lettre, un nouveau schéma de conception conjoint de précodage et de décodage pour la liaison descendante MIMO multi-utilisateurs est proposé, qui supprime les opérations itératives et permet d'obtenir de meilleures performances. Ce schéma introduit un traitement à force nulle dans le schéma de conception d'erreur quadratique moyenne minimale (MMSE) pour éviter les opérations itératives. Nous avons dérivé des précodeurs et décodeurs de forme fermée et transmis la stratégie d'allocation de puissance du schéma de conception proposé, et validé les performances du schéma de conception proposé par simulation informatique. Les résultats de la simulation montrent que le schéma de conception proposé peut atteindre un meilleur taux d'erreur sur les bits (BER) et de meilleures performances de capacité totale par rapport à un schéma de conception non itératif existant.

Abstract: In this letter, a new joint precoding and decoding design scheme for multiuser MIMO downlink is proposed which dispenses with iterative operations and can achieve better performance. This scheme introduces zero-force processing into minimum mean square error (MMSE) design scheme to avoid iterative operations. We derived closed-form precoders and decoders and transmit power allocation strategy of proposed design scheme, validated performance of proposed design scheme by computer simulation. The simulation results show that the proposed design scheme can achieve better bit error rate (BER) and sum capacity performance compared to an existing non-iterative design scheme.
