The present disclosure teaches a method and system for intelligent data management. The wireless charging system selects the transmitting coil aligned with the receiving coil most accurately for transmitting electromagnetic energy in order to improving the energy conversion efficiency between the transmitting coil and the receiving coil. The signal processor 12 performs signal processing which is based on the second signal to generate a third signal alleviated in distortion as compared to the second signal. The difference values are modeled by means of at least two difference parameters whose sum represents a perpendicular spacing between the tangential conical substitute element and a spatial coordinate. Following the ICF, the signal is de-spread sliced, re-spread and convolved with the ICF echoes.
