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). ...
RRQR based closed-form blind carrier offset estimator for OFDM systems

Qasaymeh, M.M.; Nizar, T.; Hiren, G.; Sawan, M. Edwin; Pendse, Ravi (IEEE, 2009-05-25)

Carrier Frequency Offset (CFO) is one of the major drawbacks of the Multi Carrier Modulation (MCM) technique. Blind, semiblind and data-aided techniques have been introduced to estimate the CFO. In this paper, a new blind ...
Subspace based blind CFO estimation for OFDM by exploiting used carriers

Hiren, G.; Qasaymeh, M.M.; Tayem, N.; 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 ...
