SUMMARY:Séminaire de Nicolas Petrochilos (CReSTIC\, URCA)
DESCRIPTION:Speaker: Nicolas Petrochilos\, CReSTIC\, Université de Reims C
 hampagne-Ardenne (France)\nTitle: Cardio-Respiratory separation using non-
 uniform temporal alignment\nLocation: SiMul meeting room\, Faculté des Sc
 iences et Technologies\, Henri Poincaré Building\, 4th floor\nAbstract:\n
 Using a Doppler radar to monitor the heartbeat activity of a patient is no
 t the most straightforward approach. But an important benefit is that it c
 an be operated as a remote sensing operation in rare cases where it is nec
 essary. In doing so\, the acquired signal corresponds to the chest displac
 ement\, which is the combination of the respiratory signal and the cardiac
  one. Even assuming that the combination is linear\, several challenges re
 main: The noise power is quite high and not white\, the power of the respi
 ratory signal is at least 20 dB higher than the heart\, and array source s
 eparation is not effective. Fortunately\, the heartbeat signal can be desc
 ribed as a repeating template which frequency or phase [1] is randomly slo
 wly varying. Using this information and applying a non-uniform temporal al
 ignment\, can some separation be done?\n\n[1] P. E. McSharry\, G. D. Cliff
