    Statistical Performance of a TFD based Detection Scheme (1998)
    Springer
    Multidimensional systems and signal processing 9 (1998), S. 403-409 
    Details
    ISSN: 1573-0824
    Keywords: time-frequency distributions ; robust detection
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Abstract This paper proposes a robust signal detection procedure based on generalised patterns in time-frequency space. The paper derives a non-linear time domain correlation process which is equivalent to a time-frequency based detection scheme. The performance of this robust detection scheme in the additive white Gaussian noise case is evaluated with the aid of receiver operating curves. Some examples are given which show that the proposed procedure under nominal conditions does not perform as well as standard detection scheme (ie matched filter) but gives better performance when the measured signal deviates from its nominal model.

    Stationary discrete-time covariance factorization using Newton-Raphson iteration (1992)
    Springer
    Mathematics of control, signals, and systems 5 (1992), S. 263-279 
    Details
    ISSN: 1435-568X
    Keywords: Spectral factorization ; Covariance factorization ; Newton-Raphson ; Wiener-Hopf equations ; Error localization
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology , Mathematics , Technology
    Notes: Abstract The solution to the problem of factorization of the covariance function of a stationary, discrete-time process is obtained by using a Newton-Raphson procedure which converges quadratically inl 1 provided the initial iterate is chosen suitably. The existence of a suitable initial iterate is guaranteed by an approximation result. An application to error localization in spectral factorization is suggested.
