Applicability of acoustic noise correlation for structural health monitoring in nondiffuse field conditions

Emmanuel Moulin, Najib Abou Leyla, Jamal Assaad, Sébastien Grondel

Ambient noise correlation offers an elegant way of passively caracterize a medium. The principle is that in diffuse field condition, Green’s function between two sensors can be retrieved from the cross-correlated received signals. Here, the technique is applied in conditions where convergence…

Channel estimation of OFDM system for high data rate communications on mobile environments

Boudali Ouarzazi, Marion Berbineau, Iyad Dayoub, Atika Rivenq

One of the main challenges of the 4th generation wireless systems is to provide high data rates in mobile environments. In these 4G products, WiMax (worldwide interoperability for microwave access) and LTE (long term evolution) will be the platform technologies. The rapid development of the…

Enhanced performances of MIMO transmissions over correlated channels system by using adaptive bit and power allocation on eigenmodes

Imade Fatani, Mohamed Gharbi, Marie Zwingelstein, Patrick Corlay, Marion Berbineau, François-Xavier Coudoux

In this paper, we propose the use of bit and power allocation procedure to optimize the use of eigenmodes for multiple antenna systems. We design an adaptive algorithm that exploit the Channel State Information (CSI) available at the transmitter by adapting the transmitted signals in order to…
