Title (EN) ESTIMATING NOISE AT ONE FREQUENCY BY SAMPLING NOISE AT OTHER FREQUENCIES
(FR) ESTIMATION DE BRUIT A UNE FREQUENCE PAR ECHANTILLONNAGE DU BRUIT A D'AUTRES FREQUENCES
Abstract: front page image
(EN)A method, apparatus and computer program for improving the signal-to- noise ratio of a signal S(t), S(t) containing Signal and noise, are disclosed. A measurement of S(t) at a frequency-of-interest is obtained. Noise measurements of S(t) at one or more noise frequencies where the Signal portion of S(t) is expected to be small are obtained. The noise at the frequency-of-interest is estimated using the noise measurements at the one or more noise frequencies. The estimated noise is subtracted from the measurement of S(t) at the frequency-of-interest.
(FR)L'invention concerne un procédé, un appareil et un programme informatique permettant d'améliorer le rapport signal-bruit d'un signal S(t), S(t) représentant le signal et le bruit. Une mesure de S(t) à une fréquence d'intérêt est obtenue. Les mesures de bruit de S(t) à une ou plusieurs fréquences de bruit auxquelles la partie signal de S(t) prévue est réduite sont obtenues. Le bruit à la fréquence d'intérêt est estimé à l'aide des mesures de bruit auxdites fréquences de bruit. Le bruit estimé est soustrait de la mesure de S(t) à la fréquence d'intérêt.
