DATA INTERPOLATION AND RESAMPLING

摘要

According to an example, a method for data interpolation and resampling may include receiving timestamps t s [m] for a sensor disposed in a network, where m is an interval for the received timestamps t s [m], receiving values of a signal x[m] corresponding to the timestamps t s [m] from the sensor, and determining, by a processor, values of the signal x[m] at a new set of time values t d [m] based on the timestamps t s [m] and the values of the signal x[m] corresponding to the timestamps t s [m]. The values of the signal x[m] at the new set of time values t d [m] may be determined by using a frequency domain approach that uses a phase shift to compensate for a time offset between the new set of time values t d [m] and the timestamps t s [m].
