  • An algorithm for the two dimensional FFT 

    Hoyer, E.A.; Berry, W. (IEEE, 1977-05-01)
    Conventional two dimensional fast Fourier transforms become very slow if the size of the matrix becomes too large to be contained in memory. This is due to the transposition of the matrix that is required. This new algorithm ...
  • High resolution joint time delay and frequency estimation 

    Heba, S.; Hiren, G.; Qasaymeh, M.M.; Nizar, T.; Sawan, M. Edwin; Pendse, Ravi (IEEE, 2009-03-30)
    Joint Time Delay and Frequency Estimation (JTDFE) problem of complex sinusoidal signals received at two separated sensors is an attractive problem that has been studied for many engineering applications. In this paper, the ...
  • Output feedback design of singularly perturbed discrete-time systems 

    Oloomi, Hossein; Alyatim, Amjad; Sawan, M. Edwin (IEEE, 1986-06-18)
    The output feedback regulator design for linear shift-invariant discrete-time systems possessing the two-time-scale property is considered. An approximating quadratic performance index is derived, reflecting a two-time-scale ...
  • Rank revealing QR factorization for jointly time delay and frequency estimation 

    Qasaymeh, M.M.; Hiren, G.; Nizar, T.; Pendse, Ravi; Sawan, M. Edwin (IEEE, 2009-04-26)
    The rank-revealing QR factorization (RRQR) is a valuable tool in numerical linear algebra because it provides accurate information about rank and numerical null-space. In this paper, we addressed the problem of estimating ...
  • Time delay estimator for frequency hopping system using rank-revealing triangular factorization 

    Hiren, G.; Tayem, N.; Pendse, Ravi; Sawan, M. Edwin (IEEE, 2009-04-26)
    In this paper, the multipath time delay estimation (TDE) problem for a slow frequency hopping (SFH) system using rank revealing QR factorization method (RRQR) is considered. It gives precious information about numerical ...
