This item is printed on demand - it takes 3-4 days longer - Neuware -Récemment, une convergence mondiale s'est produite pour l'utilisation du multiplexage par répartition en fréquence orthogonale (OFDM) en tant que technologie émergente pour les débits de données élevés. En particulier, de nombreuses normes sans fil (Wi-Max, IEEE802.11a, LTE, DVB) ont adopté la technologie OFDM comme moyen d'augmenter considérablement les communications sans fil futures. Il est proposé que les systèmes d'antennes intelligentes à formation de faisceau multiple utilisant la technique OFDM puissent offrir une largeur de bande variable, une protection améliorée pour l'angle d'arrivée dans la quantité calculée de différence de phase. Dans cet article, nous présentons un système d'antenne intelligente à formation de faisceau multiple basé sur DVB-T2. DVB-T2 est une norme OFDM. Pour cela, nous utilisons deux techniques, à savoir la SMI et la FFT. En utilisant la technique SMI pour la formation de faisceau, le temps de calcul requis est plus important et un nombre maximum de multiplicateurs complexes est utilisé. Pour réduire cela, l'algorithme FFT est proposé ici pour augmenter le débit et accomplir la formation de faisceau numérique et l'AOA. Le système proposé est axé sur la conception de formes d'onde de communication large bande à formation de faisceau numérique à l'aide de FPGA. 68 pp. Französisch.…
