  • Method of determining impulse responses from a medium in relation to the transmission of waves between different points
    Patent number: 7656748
    Abstract: The invention relates to a method of determining impulse responses from a medium (2) in relation to the transmission of waves between different points (T1-TN). The inventive method consists in: transmitting waves in the medium by generating, at each point j, signals ei(t) each comprising n elementary signals with respective frequencies which are spaced apart in pairs by an interval ?f and which are different from the frequencies of the elementary signals corresponding to the other points; receiving signals rj(t) at points j after the transmission of the aforementioned waves in the medium; and calculating each impulse response hij(t) from a correlation signal between signal ei(t) transmitted at point i and signal rj(t) received at point j.
