FRFT and Cyclic Prefix Refinement for Coarse-to-Fine Doppler Estimation in Coded OFDM Underwater Acoustic Communications
In underwater acoustic (UWA) orthogonal frequency division multiplexing (OFDM) systems, the orthogonality among subcarriers is highly susceptible to Doppler-induced scaling, leading to severe inter-carrier interference (ICI). This paper proposes a coarse-to-fine Doppler estimation approach for coded...
