Methods and systems to resolve cyclic ambiguity of a scattered-pilot based channel impulse response as a function of transmission parameter signalling (TPS), such as in a single frequency network, including to zero-pad a first orientation of the channel impulse response to an interval of an effective symbol duration of the multi-carrier signal, compute a channel frequency response from the zero-padded first orientation of the channel impulse response, and correlate components of the channel frequency response corresponding to frequencies of TPS carriers with raw channel frequency response data of obtained from the TPS carriers. Frequency response components of multiple zero-padded orientations of the channel impulse response may be correlated with the raw TPS carrier data to identify an optimum orientation of the channel impulse response. Frequency response components of subsequent zero-padded orientations may be iteratively computed from components of preceding orientations.
