Abstract: Apparatuses (and methods of manufacturing same), systems, and methods for channel interpolation/estimation and/or frequency tracking suitable for a receiver in a high speed single frequency network (HS-SFN) scenario are described. In one aspect, an estimated frequency offset (FO) correction is calculated for a received signal using at least an FO estimation provided by an automatic frequency control (AFC) in a first feedback loop and a channel estimate is calculated using at least the estimated FO and one or more channel parameter estimates from the AFC in a second feedback loop. In another aspect, a phase locked loop (PLL) receives an lth orthogonal frequency division multiplexing (OFDM) symbol and produces a per-tap phase value for each tap i of the lth OFDM symbol. The per-tap phase values of the lth OFDM symbol are used to generate the PLL output, which is also used as input to a feedback loop.
