Abstract
A magnetic field communication method and apparatus using a giant magnetoimpedance (GMI) magnetometer are disclosed. The magnetic field communication apparatus includes a GMI magnetometer configured to detect a first communication signal based on a received magnetic field signal, a first signal extractor configured to extract a second communication signal comprising a message signal from the first communication signal, a second signal extractor configured to extract a third communication signal by removing a magnetization frequency signal from the second communication signal, and a third signal extractor configured to extract the message signal by removing a carrier wave frequency signal from the third communication signal.
