    • Blind carrier frequency offset estimator for discrete multi tone system 

      Qasaymeh, Mahmoud Mohammad; Gami, Hirenkumar; Shatnawi, Heba Awad Addad; Pendse, Ravi; Sawan, M. Edwin (Wichita State University. Graduate School, 2009-05-01)
      In this paper, a new blind Carrier Frequency Offset (CFO) estimation algorithm for Discrete Multi Tone (DMT) system is obtained by introducing the Propagator Method (PM) in conjunction with the wellknown MUSIC based high ...
    • An efficient carrier offset estimator for multicarrier modulation system 

      Gami, Hirenkumar; Shatnawi, Heba Awad Addad; Qasaymeh, Mahmoud Mohammad; Pendse, Ravi; Sawan, M. Edwin (Wichita State University. Graduate School, 2009-05-01)
      In this paper, we proposed a closed-form solution for blind Carrier Frequency Offset (CFO) estimation employing the Rank-Revealing QR triangular factorization Method (RRQR) for Multicarrier Modulation system. The advantage ...
    • An improved frequency estimator 

      Shatnawi, Heba Awad Addad; Qasaymeh, Mahmoud Mohammad; Gami, Hirenkumar; Sawan, M. Edwin (Wichita State University. Graduate School, 2009-05-01)
      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) ...
    • 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 ...
    • Signal parameter estimation methods: The non-eigenvector based approach 

      Gami, Hirenkumar (Wichita State University, 2009-12)
      An idea behind this dissertation is the estimation of signal parameters of a radio channel snapshot. The focal point here to utilize the high resolution estimation capabilities of subspace based methods in association ...
