    • Joint time delay and frequency estimation without eigen-decomposition 

      Qasaymeh, Mahmoud Mohammad; Gami, Hirenkumar; Tayem, Nizar Abdel-Hafeeth Mohammad; Sawan, M. Edwin; Pendse, Ravi (2009-05)
      In this letter, we addressed the problem of estimating the time delay and the frequencies of noisy sinusoidal signals received at two spatially separated sensors. We employ the Propagator Method (PM) in conjunction with ...
    • Propagator method for joint time delay and frequency estimation 

      Qasaymeh, Mahmoud Mohammad; Hiren, G.; Tayem, Nizar Abdel-Hafeeth Mohammad; 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) ...
    • Subspace based blind CFO estimation for OFDM by exploiting used carriers 

      Hiren, G.; Qasaymeh, Mahmoud Mohammad; Tayem, Nizar Abdel-Hafeeth Mohammad; Pendse, Ravi; Sawan, M. Edwin (IEEE, 2009-03-30)
      Orthogonal frequency division multiplexing (OFDM) is a promising technique to handle impairments of multipath channel. Alternatively, one of its major drawbacks is the drift in reference carrier, which is known as carrier ...
    • Time delay estimator for frequency hopping system using rank-revealing triangular factorization 

      Hiren, G.; Tayem, Nizar Abdel-Hafeeth Mohammad; 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 ...
