N2 - In this paper, a joint data-aided channel and frequency offset estimator is proposed for doubly-selective fading channels. The joint estimator is based on the B-spline model approximating the fading process and the dichotomous search frequency estimation technique. The estimator relies on the Bayesian approach. It is examined for different scenarios in Rayleigh fading channels. Simulation results show that the proposed estimator achieves a high accuracy performance, which is close to that with perfect knowledge of the frequency offset, over a wide range of signal to noise ratios, for different Doppler frequencies and throughout all the frequency acquisition range.
