Dans les systèmes de communication conventionnels à entrées multiples à sorties multiples (MIMO), la plupart des méthodes de sélection d'antenne considérées ne conviennent qu'aux systèmes unipolarisés spatialement séparés sous un canal à évanouissement de Rayleigh dans des conditions sans visibilité directe (NLOS). Il existe quelques schémas de sélection d'antenne pour le système à polarisation croisée en condition LOS et canal à évanouissement de Rice, et aucun schéma de sélection d'antenne pour le canal MIMO avec à la fois LOS et NLOS. Dans le cas pratique du canal MIMO, l'influence des conditions LOS et NLOS dans le canal peut varier de temps en temps en fonction des paramètres du canal et des mouvements de l'utilisateur dans le système. En fonction de ces influences et de l'état du canal, un système unipolaire peut surpasser un système à polarisation croisée. Ainsi, nous devrions considérer ce type d’environnement pratique de canal MIMO lors du développement du schéma de sélection d’antenne. De plus, aucun travail de recherche n’a été effectué pour réduire la complexité de la sélection d’antenne pour ce type d’environnement pratique de canal MIMO. Dans cet article, une complexité réduite dans la sélection de l'antenne est proposée pour obtenir un débit plus élevé dans l'environnement pratique du canal MIMO. Dans le schéma proposé, des antennes polarisées appropriées sont sélectionnées sur la base du calcul de la décomposition en valeurs singulières (SVD) de la matrice de canal, puis un chargement de bits adaptatif est appliqué. Les résultats de la simulation montrent que le débit du système peut être amélioré sous la contrainte du BER cible et de la puissance de transmission totale du système MIMO.

Abstract: In the conventional multi-input multi-output (MIMO) communication systems, most of the antenna selection methods considered are suitable only for spatially separated uni-polarized system under Rayleigh fading channel in non-line of sight (NLOS) condition. There have a few antenna selection schemes for the cross-polarized system in LOS condition and Ricean fading channel, and no antenna selection scheme for the MIMO channel with both LOS and NLOS. In the practical MIMO channel case, influence of LOS and NLOS conditions in the channel can vary from time to time according to the channel parameters and user movement in the system. Based on these influences and channel condition, uni-polarized system may outperform a cross-polarized. Thus, we should consider this kind of practical MIMO channel environment when developing the antenna selection scheme. Moreover, no research work has been done on reducing the complexity of antenna selection for this kind of practical MIMO channel environment. In this paper, reduced complexity in antenna selection is proposed to give the higher throughput in the practical MIMO channel environment. In the proposed scheme, suitable polarized antennas are selected based on the calculation of singular value decomposition (SVD) of channel matrix and then adaptive bit loading is applied. Simulation results show that throughput of the system can be improved under the constraint of target BER and total transmit power of the MIMO system.
