  • Efficient structure-based carrier offset estimator for OFDM system 

    Hiren, G.; Qasaymeh, M.M.; Nizar, T.; Pendse, Ravi; Sawan, M. Edwin (IEEE, 2009-04-26)
    In this paper, we proposed a closed form solution for blind orthogonal frequency division multiplexing (OFDM) carrier frequency offset (CFO) estimation employing the rank- revealing QR triangular factorization method (RRQR). ...
  • Propagator method for joint time delay and frequency estimation 

    Qasaymeh, M.M.; Hiren, G.; Tayem, N.; Pendse, Ravi; Sawan, M. Edwin (IEEE, 2008-10-26)
    A novel method of estimating the differential delay of a sinusoidal signal is considered. The new method utilizes the propagator method (PM) which does not require the eigen-decomposition of the cross-spectral matrix (CSM) ...
  • 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 ...
