  • Method and apparatus for estimating a frequency domain representation of a signal
    Patent number: 10090872
    Abstract: A signal processing method for estimating a frequency domain representation of signal from a series of samples distorted by an instrument function, the method comprising obtaining the series of samples; obtaining a set of coefficients that fit a set of basis functions to a complex exponential function wherein the set of basis functions comprises a plurality of basis functions each defined by a shifted version of the instrument function in a signal domain; estimating the frequency domain representation of the signal based on the series of samples and the coefficients. This is wherein the estimate of the instrument function is based on a characterization of the instrument function in the frequency domain at frequencies associated with the complex exponential function.
