Abstract
Systems, methods, and devices estimate timing values for data transmission associated with wireless communications devices. Methods include receiving, at a transceiver of a wireless communications device, at least one symbol included in a data transmission, obtaining a plurality of samples of the at least one symbol, and generating, using one or more processors, a plurality of correlation values for each of the plurality of samples. Methods further include generating, using the one or more processors, a multi-sample interpolation model based on at least some of the plurality of correlation values and determining, using the one or more processors, an estimated maximum correlation value and a temporal offset value based on the multi-sample interpolation model, the temporal offset value being used for a time of arrival computation.
