Abstract The problem on the time-frequency parameters estimation in the mobile channel is considered in this paper. For this aim, a blind algorithm is proposed, which is based on the cyclostationarity property of the received signal. Theoralic analysis and simulation results are provided to show that this algorithm is suitable for a frequency selective fading channel. When compared with the other method, its ability to estimate a larger frequency offset and higher estimation resolution are shown.
