Riassunto

Des recherches ont �t� men�es sur le d�veloppement d'algorithmes de traitement des signaux pour l'�volution � long terme (LTE), ce qui n�cessite un environnement de simulation r�aliste, flexible et conforme aux normes. Pour faciliter les comparaisons avec les travaux d'autres groupes de recherche, un tel environnement de simulation devrait id�alement �tre accessible au public. Le LTE est l'�volution de l'UMTS qui permettra de fournir des services multim�dias de haute qualit� de la prochaine g�n�ration en fonction des attentes des utilisateurs. �tant donn� que l'�valuation des performances du LTE n�cessite des simulations au niveau de la liaison et du syst�me, cet ouvrage pr�sente un outil logiciel permettant de simuler la liaison descendante du LTE bas�e sur la technologie OFDM avec traitement d'antenne MIMO. Ce simulateur contient les algorithmes MIMO, les mod�les de canaux spatiaux et les sch�mas de modulation et de codage pour le LTE. Le r�sultat de ce simulateur permet d'�valuer les performances de la liaison LTE OFDM-MIMO dans diff�rents environnements et de cr�er des tables de correspondance au niveau de la liaison qui serviront d'entr�e � un futur simulateur de niveau de syst�me LTE. Tous ces �l�ments, ainsi que d'autres discussions, permettent au lecteur d'avoir une image claire de la couche physique LTE et des techniques utilis�es dans le syst�me de communication LTE.
