  • Reducing noise in a sequence of data by linear and non-linear estimation
    Patent number: 8781041
    Abstract: A method of reducing noise in a sequence of data by linear and non-linear estimation. The method includes receiving a noisy sequence of data indicative of a sequence of physical events; applying a non-linear technique to the noisy sequence to obtain an approximation of a noise-free sequence of data; subtracting the approximation from the noisy sequence to obtain an estimate of noise in the noisy sequence of data; applying a linear technique to the estimate of noise to obtain a filtered sequence; and adding the filtered sequence to the approximation of the noise-free sequence to obtain a reduced-noise sequence of data indicative of the sequence of physical events.
