Abstract
Sensor data, transferred by wireless sensor networks, must often be resampled for correcting missing samples or timing deviations. The direct application of the well-known Shannon theorem is limited to uniform sampling. For the non-uniform case, the resampling accuracy can be improved by Local Regression. Several cases, such as low/high signal frequency and noise were tested in combination with different scales of non-uniformity from missing single samples to fully arbitrary sampling.
