Recent studies have numerically demonstrated the possible advantages of the
asynchronous non-orthogonal multiple access (ANOMA) over the conventional synchronous …

We analyze the pair production of charged particles in two-dimensional Anti-de Sitter space
(AdS 2) with a constant, uniform electric field. We compute the production rate both at a semi …

In this paper, we study the sensitivity of uplink and downlink MC-DS-CDMA to carrier
frequency offsets, assuming orthogonal spreading sequences. For both uplink and downlink …

Electrical impedance tomography (EIT) is used to determine the spatial conductivity
distribution of a measurement environment that involves several applications in the areas of …

New air interfaces are currently being developed to meet the high spectral efficiency
requirements of the emerging wireless communication systems. Multicarrier code-division …

Les futurs systèmes de radiocommunications devront proposer des services nécessitant des
transferts de données à haut débit, tout en garantissant une grande mobilité aux utilisateurs …

To better answer the user needs, new air interfaces are currently being selected for the
emerging wireless communication systems. OFDM and SC-FDE are two interesting …

We consider the effect of carrier frequency offset on the performance of MC-CDMA and MC-
DS-CDMA, which are both combinations of the multicarrier transmission technique and the …

Dans le cadre des systèmes de communications radio mobiles de la 4ème génération, on s'
est intéressé aux systèmes combinant les techniques d'étalement par les codes et de …

Les systèmes numériques de communications connaissent un essor considérable sous
l'impulsion d'une demande de plus en plus pressante de mobilité, de diversité des services …
