“…The normalized Doppler is 0.1, which is the product between the actual Doppler and the symbol duration, and the results are averaged over 10 2 independent realizations of the experiments. For comparison, the RMSE using existing Doppler estimators from [2], [3], [5], [6] are also shown. And the estimation performance without a pilot signal is also considered in this experiment.…”

“…Several methods have been proposed to acquire the Doppler information including a maximum likelihood estimator [1], an estimator that uses the cyclostationarity of the transmitted symbols [2], and an estimator that is based on the Fourier transform of the autocorrelation of the channel [3]. Various Doppler spread estimators are reviewed in [4], among which the level crossing rate (LCR) method and the covariance based method are emphasized.…”

Doppler spread causes a significant performance degradation in fast-fading mobile communication systems. This paper proposes a novel Doppler estimation scheme that uses a damped sinusoid to approximate the autocorrelation of the fading channel. Subsequently, an Autoregressive (AR) model is used for the damped sinusoid and the parameters of the model are related to the Doppler value. The superiority of the proposed estimation method over existing state-of-the-art methods is demonstrated using numerical simulations. The proposed scheme is promising in vehicular communication systems.Index Terms-Doppler spread estimation, OFDM system, fading channel.
