Propagation delays are intensively used for Structural Health Monitoring or Sensor Network Localization. In this paper, we study the performances of acoustic propagation delay estimation between two sensors, using sources of opportunity only. Such so

This paper is devoted to blind separation of combustion noise and piston-slap in diesel engines. The two phenomena are recovered only from signals issued from accelerometers placed on one of the cylinders. A blind source separation (BSS) method is de

Geoacoustical parameters estimation with impulsive and boat-noise sources

Autor: Jean-Louis Lacoume, Jerome Mars, Barbara Nicolas

Publikováno v: IEEE Journal of Oceanic Engineering. 28:494-501

Localization is a crucial issue in underwater acoustics: when an underwater source is detected, the next step consists of localizing it. To do this, environmental parameters must be known or estimated. How can we estimate these parameters? As underwa

International audience; In this study, we consider the use of seismic sensors for footstep localization in indoor environments. A popular strategy of localization is to use the measured differences in arrival times of source signals at multiple pairs

Statistics for complex variables and signals — Part II: signals

Autor: Jean-Louis Lacoume, M. Gaeta, Pierre-Olivier Amblard

Publikováno v: Signal Processing. 53:15-25

In this paper, we study the higher-order statistics of complex stationary signals. In a first part, we define precisely the multicorrelations and multispectra of complex signals. Different properties of these tools are put in evidence for certain cla
