Abstract
In this work, we present a simple approach to estimate and correct the carrier offset in an orthogonal frequency division multiplexing (OFDM) system. The approach leads to a computationally and statistically efficient estimator for the carrier offset. Computer simulations verify that the estimation accuracy is comparable to the Cramer-Rao bound (CRB). We demonstrated that by incorporating the estimated carrier offset (obtained using reasonable frames of OFDM data) in the demodulation process, the bit-error-rate (BER) can approach that of the ideal OFDM system with no carrier offset.
